Question

I am very confused on how to even begin figuring out the below problems:

1. Naomi has earned $54.00 mowing lawns the past two days. She worked 2 1/2 hours yesterday and 4 1/4 hours today. If Naomi is paid the same amount for every hour she works, how much does she earn per hour to mow lawns?

2. An art teacher has 1 1/2 pounds of red clay and 3/4 pound of yellow clay. The teacher mixes the red clay and yellow clay together. Each student in the class needs 1/8 pound of the clay mixture to finish the assigned art project for the class. How many students can get enough clay to finish the project?

Answer 1

rate per hour is

#dollars / #hours

(1 1/2 + 3/4)/(1/8)
or 8 * (3/2 + 3/4) = ?

Answer 2

I don't understand your answer? Which one is it pertaining to?

Can you walk me through this step by step for problem number one please?

Answer 3

she worked 2 2/4 + 4 1/4 = 6 3/4 hours

54/6.75 = dollars/hour

=====================================

total amount of clay = 1 2/4 + 3/4
= 1 5/4 = 2 1/4 = 9/4

9/4 / 1/8 = 8 ( 9/4 ) = 18

Answer 4

For problem number one how did you get 2 2/4?

Answer 5

2 1/2 = 2 2/4

Answer 6

For problem number two how did you get 1 2/4?

Answer 7

Now I am really confused.

The problem is as follows:

An art teacher has 1 1/2 pounds of red clay and 3/4 pound of yellow clay. The teacher mixes the red clay and yellow clay together. Each student in the class needs 1/8 pound of the clay mixture to finish the assigned art project for class. How many students can get enough clay to finish the project?

Answer 8

just think about it. How much clay was used?

1 1/2 + 3/4 = 1 2/4 + 3/4 = 1 5/4 = 9/4 lbs

Now, if each student uses 1/8 lb, the 1 whole pound is enough for 8 students, right?

So 8 * 9/4 = 72/4 = 18 students can be satisfied.

Or, since 1/4 lb = 2/8 lb, each 1/4 lb of clay will provide 2 students. Since there are 9/4 lb of clay, that's enough for 9*2 = 18 students.
