Use the RDW process to solve.

Question 1.

Sue ran \(\frac{9}{10}\) mile on Monday and \(\frac{7}{10}\) mile on Tuesday. How many miles did Sue run in the 2 days?

Answer:

The number of miles did Sue run in the 2 days = 1.6 miles.

Explanation:

In the above-given question,

given that,

Sue ran \(\frac{9}{10}\) mile on Monday.

9/10 = 0.9.

\(\frac{7}{10}\) mile on Tuesday.

7/10 = 0.7.

0.9 + 0.7 = 1.6.

the number of miles did sue run in the 2 days = 1.6 miles.

Question 1.

Mrs. Smith took her bird to the vet. Tweety weighed 1\(\frac{3}{10}\) pounds. The vet said that Tweety weighed \(\frac{4}{10}\) pound more last year. How much did Tweety weigh last year?

Answer:

Explanation:

In the above-given question,

given that,

Mrs. Smith took her bird to the vet.

Tweety weighed 11\(\frac{3}{10}\) pounds.

the vet said that Tweety weighed \(\frac{4}{10}\) pound more last year.

4/10 = 0.4.

so the tweety weigh last year = 0.4 pounds.

Question 2.

Hudson picked 1\(\frac{1}{4}\) baskets of apples. Suzy picked 2 baskets of apples. How many more baskets of apples did Suzy pick than Hudson?

Answer:

The more baskets of apples did Suzy pick than Hudson = 0.75.

Explanation:

In the above-given question,

given that,

Hudson picked 1\(\frac{1}{4}\) baskets of apples.

Suzy picked 2 baskets of apples.

1(1/4) = 4 + 1/4.

5/4 = 1.25.

2 – 1.25 = 0.75.

so the more baskets of apples did Suzy pick than Hudson = 0.75.

Question 1.

Isla walked \(\frac{3}{4}\) mile each way to and from school on Wednesday. How many miles did Isla walk that day?

Answer:

The number of miles did Isla walk that day = 1.5 miles.

Explanation:

In the above-given question,

given that,

Isla walked \(\frac{3}{4}\) mile each way to and from school on wednesday.

so the number of miles did Isla walk that day = 1.5 miles.

Question 2.

Zach spent \(\frac{2}{3}\) hour reading on Friday and 1\(\frac{1}{3}\) hours reading on Saturday. How much more time did he read on Saturday than on Friday?

Answer:

The more time he read on Saturday than on Friday = 0.67.

Explanation:

In the above-given question,

given that,

Zach spent \(\frac{2}{3}\) hour reading on friday.

1\(\frac{1}{3}\) hours reading on Saturday.

2/3 = 0.66.

1(1/3) = 3 + 1/3.

4/3 = 1.33.

1.33 – 0.66.

0.67.

so the much more time he read on Saturday than on Friday = 0.67.

Question 3.

Mrs. Cashmore bought a large melon. She cut a piece that weighed 1\(\frac{1}{8}\) pounds and gave it to her neighbor. The remaining piece of melon weighed \(\frac{6}{8}\) pound. How much did the whole melon weigh?

The whole melon weighs = 1.875.

Explanation:

In the above-given question,

given that,

Mrs. Cashmore bought a large melon.

She cut a piece that weighed 1\(\frac{1}{8}\) pounds and gave it to her neighbor.

The remaining piece of melon weighed \(\frac{6}{8}\) pound.

1(1/8) = 8 + 1/8.

9/8.

9/8 + 6/8 .

1.125 + 0.75.

1.875.

so the whole melon weighs = 1.875.

Question 4.

Ally’s little sister wanted to help her make some oatmeal cookies. First, she put \(\frac{5}{8}\) cup of oatmeal in the bowl. Next, she added another \(\frac{5}{8}\) cup of oatmeal. Finally, she added another \(\frac{5}{8}\) cup of oatmeal. How much oatmeal did she put in the bowl?

Answer:

The quantity of oatmeal did she put in the bowl = 1.875 cookies.

Explanation:

In the above-given question,

given that,

Ally’s little sister wanted to help her make some oatmeal cookies.

First, she put \(\frac{5}{8}\) cup of oatmeal in the bowl.

Next, she added another \(\frac{5}{8}\) cup of oatmeal.

Finally, she added another \(\frac{5}{8}\) cup of oatmeal.

5/8 + 5/8 + 5/8.

0.625 + 0.625 + 0.625.

1.875.

so the quantity of oatmeal she put in the bowl = 1.875 cookies.

Question 5.

Marcia baked 2 pans of brownies. Her family ate 1\(\frac{5}{6}\) pans. What fraction of a pan of brownies was left?

Answer:

The fraction of a pan of brownies was left = 0.17.

Explanation:

In the above-given question,

given that,

Marcia baked 2 pans of brownies.

Her family ate 1\(\frac{5}{6}\) pans.

1(5/6) = 6 + 5/6.

11/6 = 1.83.

2 – 1.83.

0.17.

so the fraction of a pan of brownies was left = 0.17.

Question 6.

Joanie wrote a letter that was 1\(\frac{1}{4}\) pages long. Katie wrote a letter that was \(\frac{3}{4}\) page shorter than Joanie’s letter. How long was Katie’s letter?
