Equivalent Fractions
Use the model to write an equivalent fraction.
Question 1.
\(\frac{4}{6}=\frac{2}{3}\)
Explanation:
The first image has 4 parts shaded out of 6 parts. Divide 8/10 with 2. You will get 2/3. That means 2 parts are shaded out of 3 parts.
Question 2.
\(\frac{3}{4}\) = \(\frac{□}{□}\)
Answer: \(\frac{3}{4}\) = \(\frac{6}{8}\)
Explanation:
The first image has 3 parts shaded out of 4 parts. Multiply 8/10 with 2. You will get 6/8. That means 6 parts are shaded out of 8 parts.
Tell whether the fractions are equivalent. Write = or ≠.
Question 3.
\(\frac{8}{10}\) _____ \(\frac{4}{5}\)
Answer: \(\frac{8}{10}\) = \(\frac{4}{5}\)
Explanation:
Multiply the numerator and denominator of 4/5 with 2.
8/10 = (2/2) × (4/5)
= 8/10
So, 8/10 = 4/5.
Question 4.
\(\frac{1}{2}\) _____ \(\frac{7}{12}\)
Answer: \(\frac{1}{2}\) ≠ \(\frac{7}{12}\)
Explanation:
Multiply the numerator and denominator of 1/2 with 6
1/2 = (6/6) x (1/2)
= (6/12)
So, 1/2 ≠ 7/12
Question 5.
\(\frac{3}{4}\) _____ \(\frac{8}{12}\)
Answer: \(\frac{3}{4}\) ≠ \(\frac{8}{12}\)
Explanation:
Multiply the numerator and denominator of 3/4 with 3.
3/4 = (3/3) × (3/4)
= (9/12)
So, 3/4 ≠ 8/12
Question 6.
\(\frac{2}{3}\) _____ \(\frac{4}{6}\)
Answer: \(\frac{2}{3}\) = \(\frac{4}{6}\)
Explanation:
Multiply the numerator and denominator of 2/3 with 2.
2/3 = (2/2) × (2/3)
= 4/6
So, 2/3 = 4/6.
Question 7.
\(\frac{5}{8}\) _____ \(\frac{4}{10}\)
Answer: \(\frac{5}{8}\) ≠ \(\frac{4}{10}\)
Explanation:
Multiply the numerator and denominator of 5/8 with 2
5 / 8 =(2/2) x (5/ 8)
= (10/16)
So, 5/8 ≠ 4/10
Question 8.

Answer:
Question 9.
\(\frac{20}{100}\) _____ \(\frac{1}{5}\)
Answer: \(\frac{20}{100}\) = \(\frac{1}{5}\)
Explanation:
Cross Multiply the 20/100 with 20/20
20/100 = (20/20) x (20/100)
= (1/5)
So, 20/100 = 1/5.
Question 10.
\(\frac{5}{8}\) _____ \(\frac{9}{10}\)
Answer: \(\frac{5}{8}\) ≠ \(\frac{9}{10}\)
Explanation:
Multiply the numerator and denominator of 5/8 with 2
5/8 = (2/2) x (5/8)
= 10/16
So, 5/8 ≠ 9/10
Question 11.

Margaret finished work = 3 /4th of her homework
Steve finished work = 10/12 of his homework
Multiply the numerator and denominator of 5/6 with 2
Then, (2/2) x (5/6) = 10/12
Then, Jamal and Steve finished the same amount of homework.
Question 12.
Sophia’s vegetable garden is divided into 12 equal sections. She plants carrots in 8 of the sections. Write two fractions that are equivalent to the part of Sophia’s garden that is planted with carrots.
Type below:
_________
Answer: 2/3 and 4/6
Explanation:
As per the given data,
Sophia’s vegetable garden is divided into 12 equal sections
She plants carrots in 8 of the sections out of 12 sections = 8/12
By simplifying the 8/12, we will get 4/6
Again simplify the 4 /6 by dividing method, you will get 2 /3
2/3 = (2/2) x (2/3)
= 4/6
Then, the equivalent fractions are 2/3, 4 /6

Question 1.
A rectangle is divided into 8 equal parts. Two parts are shaded. Which fraction is equivalent to the shaded area of the rectangle?
Options:
a. \(\frac{1}{4}\)
b. \(\frac{1}{3}\)
c. \(\frac{2}{6}\)
d. \(\frac{3}{4}\)
Answer: \(\frac{1}{4}\)
Explanation:
As per the given data,
A rectangle is divided into 8 equal parts
Two parts are shaded
Then, the shaded area of rectangle = 2/8
By simplifying the 2/8, you will get 1/4
So, the shaded area of rectangle = 1/4
Thus the correct answer is option a.
Question 2.
Jeff uses 3 fifth-size strips to model \(\frac{3}{5}\). He wants to use tenth-size strips to model an equivalent fraction. How many tenth-size strips will he need?
Options:
a. 10
b. 6
c. 5
d. 3
Answer: 6
Explanation:
From the given data,
Jeff uses 3 fifth –size strips to model = 3 / 5 size strips
If he wants to use tenth – size strips to an equivalent fraction = 1 / 10 size strips
The number of strips = x
(1/10) x = 3/5
x = 30/5
then, the required number of tenth size trips = 6
Thus the correct answer is option b.

Type below:
_________
Answer: 1/3, 1/2, 2/3 and final locations
Explanation:
We have three fractions with different denominators: sixths, thirds, and halves.
The first step is to make all the denominators equal for 1/6, 1/3, 1/2.
In this case, we want sixths since LCM(2, 3, 6) = 6
since 1/3 = 2/6, and 1/2 = 3/6. Now we can start solving.
1. There are six tires at the following: 1/6, 2/6, 3/6, 4/6, 5/6, and 6/6.
2. There are three cones at the following (G.C.F.): 2/6 (or 1/3), 4/6 (or 2/3), and 6/6 (or 3/3).
3. There are two hurdles at the following (G.C.F.): 3/6 (or 1/2) and 6/6 (or 2/2).
We look for common numbers.
1. On 2/6, there are two obstacles: a tire and a cone.
2. On 3/6, there are two obstacles: a tire and a hurdle.
3. On 4/6, there are two obstacles: a tire and a cone.
4. At 6/6, there are three obstacles: a tire, cone, and a hurdle.
2/6 = 1/3
3/6 = 1/2
4/6 = 2/3
6/6 = 1
The answers are 1/3, 1/2, 2/3, and 1.

Every \(\frac{1}{2}\) hour Naomi stretches her neck; every \(\frac{1}{3}\) hour she stretches her legs; and every \(\frac{1}{6}\) hour she stretches her arms. Which parts of her body will Naomi stretch when \(\frac{2}{3}\) of an hour has passed?
Options:
a. neck and legs
b. neck and arms
c. legs and arms
d. none
Answer: legs and arms
Explanation:
Summing \(\frac{1}{2}\)‘s only gives integer values giving 1, 2, 3, 4…or
integer values +\(\frac{1}{2}\) and 0 + \(\frac{1}{2}\) = \(\frac{1}{2}\), 1 \(\frac{1}{2}\), 2 \(\frac{1}{2}\)…
So neck is excluded
Every \(\frac{1}{3}\): \(\frac{1}{3}\) + \(\frac{1}{2}\) = \(\frac{2}{3}\)
Legs will be stretched at \(\frac{2}{3}\) hour
Every \(\frac{1}{6}\): \(\frac{1}{6}\) + \(\frac{1}{6}\) + \(\frac{1}{6}\) + \(\frac{1}{6}\) = \(\frac{4}{6}\)
Divide top and bottom by 2 giving:
(4 ÷ 2)/(6 ÷ 2) = \(\frac{2}{3}\)
Arms will be stretched at \(\frac{2}{3}\) hour.
Thus the correct answer is option c.
