Sheila has 10 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 2 1/4 pounds. How many containers does she need? Complete the explanation.

5  containers

Step-by-step explanation:

Step 1

Given that

Total amount of potato salad = 10 1/2

amount of salad in each container = 2 1/4

Total number of containers = ?

Step 2

Divide the total amount of potato salad by the amount of salad each container  can hold  

 Total number of containers=10 1/2 / 2 1/4 = 21/2 x 4/9= 84/18 = 4 3/5

which can also be written as 10.5 / 2.25= 4.6  

Sheila  will need 5 containers because  4 will be filled and  additional 1 will be partially filled.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
