Question

irma needs 3 1/3 pounds of flour for her cake her measuring cup holds 1/3 pound of flour irma will need to add?

Answer 1

Explanation:

3 1/3 pounds

`3(1)/(3)=(3\ast3+1)/(3)=(9+1)/(3)=(10)/(3)`

She need 10/3 pounds of flour for her cake.

Her cup holds 1/3 pound. How many cups she needs?

We use a rule of three to solve this. So

1 cup - 1/3 pound

x cups - 10/3 pounds

Applying cross multiplication:

`(1)/(3)\ast x=(10)/(3)`
`(x)/(3)=(10)/(3)`

Now we apply cross multiplication:

3x = 3*10

3x = 30

x = 30/3

x = 10
