How many leaves were less than \(\frac{3}{8}\)ft in length?

(A) 19

(B) 30

(C) 7

(D) 9

Answer: Option B is correct.

Explanation:

The length of leaves is 1/8 and its frequency is 11.

The length of leaves is 1/4 and its frequency is 19.

The question asked was the number of leaves was less than \(\frac{3}{8}\)ft in length. To get the answer to add the length of leaves 1/8 and 1/4 and their frequencies:11+9=30.

Because 1/8 and 1/4 are less than 3/8.

Question 12.

How many more leaves are \(\frac{1}{4}\)ft than \(\frac{3}{8}\)ft and \(\frac{1}{2}\)ft combined?

(B) 30

(C) 7

(D) 9

Answer: Option D is correct.

Explanation:

The leaves of \(\frac{1}{4}\)ft and its frequency=19

The leaves of \(\frac{3}{8}\)ft and \(\frac{1}{2}\)ft combined and its frequencies are: 7+3=10.

We need to find out the number of more leaves present in 1/4 than 3/8 and 1/2=19-10=9.

**Go Math Grade 4 Unit 5 Assessment Answer Key Question 22.**

Brandon borrowed a book from the library. The data show the lengths of time Brandon read the book each day until he finished it. Explain how you would use the data to label and plot the dots on a dot plot. What is the difference between the longest time and shortest time Brandon spent reading the book?

Answer:

1. The representation must be lowest to highest.

2. Count and write the number of dots above the respective places.

3. The diagram representation is shown below:

The dot plot of 1/4 has 4 dots.

The dot plot of 1/2 has 2 dots.

The dot plot of 3/4 has 1 dot.

The dot plot of 1 has 1 dot.

In the question asked was the difference between the longest time and shortest time Brandon spent reading the book.

The longest time is 1 hour the dot is 1.

The shortest time is 1/4 hour that’s the dot is 4.

The difference is 4-1=3 hours.
