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?

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

Explanation:
In the above-given question,

The number of gallons of punch did he make in all = 13/8 gallons.

Explanation:
In the above-given question,
given that,
Marius combined $$\frac{4}{8}$$ gallon of lemonade.
$$\frac{3}{8}$$ gallon of cranberry juice.
and $$\frac{6}{8}$$ gallon of soda water to make punch for a party.
4/8 + 6/8 + 3/8.
4/8 + 6/8 = 10/8.
10/8 + 3/8 = 13/8.
the number of gallons of punch did he make in all.

Use the RDW process to solve.

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?

The Tweety weigh last year = 0.4 pounds.

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?

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.

Use the RDW process to solve.

Question 1.
Isla walked $$\frac{3}{4}$$ mile each way to and from school on Wednesday. How many miles did Isla walk that day?

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.
3/4 = 0.75.
0.75 + 0.75 = 1.5.
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?

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?

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?

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.
