One circle has 3/4 of the parts shaded

So, non- shaded parts of one circle = 1 – 3/4 = 1/4

Another circle has 2/3 of the parts shaded

Non – shaded parts = 1 – 2/3 = 1/3

We can’t draw a conclusion that in how many parts or pieces a circle can be divided

So, his sister is incorrect

Andy cut a tuna sandwich and a chicken sandwich into a total of 15 same-size pieces. He cut the tuna sandwich into 9 more pieces than the chicken sandwich. Andy ate 8 pieces of the tuna sandwich. What fraction of the tuna sandwich did he eat?

\(\frac{□}{□}\)

Answer:

\(\frac{2}{3}\)

Explanation:

Let x be the number of pieces of the chicken sandwich so that x + 9 is the number of pieces of a tuna sandwich.

There is a total of 15 same-size pieces. So, we can write as

x + (x + 9) = 15

2x + 9 = 15

2x = 6

x = 3.

This means that there ate 3 + 9 = 12 pieces of a tuna sandwich. Since Andy ate 8, then this corresponds to a fraction of 8/12 = 2/3.

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.

Morita works in a florist shop and makes flower arrangements. She puts 10 flowers in each vase, and \(\frac{2}{10}\) of the flowers are daisies.

Part A

If Morita makes 4 arrangements, how many daisies does she need? Show how you can check your answer.

_____ daisies

Answer:

8 daisies

Explanation:

If Morita makes 4 arrangements, 4 X 2 = 8.

Question 10.

Part B

Last weekend, Morita used 10 daisies to make flower arrangements. How many flowers other than daisies did she use to make the arrangements? Explain your reasoning.

_____ other flowers

Answer:

40 other flowers

Explanation:

If she used 10 daises, she must have made 5 arrangements. In each vase, she put \(\frac{2}{10}\) of the flowers are daisies. So, remaining flowers for each vase = 10 – 2 = 8. If she made 5 arrangements, 8 X 5 = 40 other flowers.

Question 12.

Regina, Courtney, and Ellen hiked around Bear Pond. Regina hiked \(\frac{7}{10}\) of the distance in an hour. Courtney hiked \(\frac{3}{6}\) of the distance in an hour. Ellen hiked 38 of the distance in an hour. Compare the distances hiked by each person by matching the statements to the correct symbol. Each symbol may be used more

than once or not at all.

Type below:

_________

Answer:

Explanation:

From the given information

Regina, Courtney, and Ellen hiked around Bear Pond

Regina hiked 7/10 of the distance in an hour

Courtney hiked 3/6 of the distance in an hour

Ellen hiked 3 /8 of the distance in an hour

Compare 7/10 and 3/6

The common denominator of 7/10 and 3/6 is 30

(7×3)/(10×3) and (3×5)/(6×5)

21/30 and 15/30

So, 21/30 > 15/30

So, 7/10 > 15/30

Compare 3/8 and 3/6

The common denominator of 3/8 and 3/6 is 24

(3×3)/(8×3) and (3×4)/(6×4)

9/24 and 12/24 = 9/24 < 12/24 = 3/8 < 3/6

Compare 7/10 and 3/8

The common denominator of 7/10 and 3/8 is 40

(7×4)/(10×4) and (3×5)/(8×5)

28/40 >15/40 = 7/10 > 3/8

Question 13.

Ramon is having some friends over after a baseball game. Ramon’s job is to make a vegetable dip. The ingredients for the recipe are given.

Part A

Which ingredient does Ramon use the greater amount of, buttermilk or cream cheese? Explain how you found your answer.

Type below:

_________

Answer:

Ramon use 5/8 cup of buttermilk and 1/2 cup cream cheese

By comparing these two ingredients

The common denominator of 5/8 and 1/2 are 8

(1×4)/(2×4) =4/8

So, 5/8 > 4/8

So, 5/8 cup buttermilk is > ½ cup cream cheese

Question 13.

Part B

Ramon says that he needs the same amount of two different ingredients. Is he correct? Support your answer with information from the problem.

______

Answer:

Ramon says that he needs the same amount of two ingredients

Yes, Ramon uses 3/4 cup parsley and 6/8 cup scallions

Multiply the 3/4 with 2

(3×2)/(4×2) = 6/8

So, Ramon uses the same amount that is 3/4 cup for parsley and scallions

Question 14.

Sandy is ordering bread rolls for her party. She wants \(\frac{3}{5}\) of the rolls to be whole wheat. What other fractions can represent the part of the rolls that will be whole wheat? Shade the models to show your work.

Type below:

_________

Answer:

Explanation:

As per the information,

Sandy is ordering bread rolls for her party

She wants 3/5 of the rolls to be whole wheat

For an equivalent fraction of 3/5, multiply with 5

(3×5)/(5×5) = 15/25

Again multiply the 15/25 with 4

(15×4)/(25×4) = 60/100

Question 15.
