Question

Paolo is using his grandmother's breakfast bar recipe. He always doubles

the amount of yogurt and oats. The recipe calls for 2 1/2 cups of
yogurt.
The total amount of yogurt and oats after doubling is 6 1/3 cups. Write an
equation to find the original amount of oats in the recipe.
I just need the equation i don't need the answer!!!! pls help me!!!!

Answer 1

`6(1)/(3)` =
`2(1)/(2)` * 2 +
`(x)/(2)`

Explanation:

lets start with what we know.

the recipe calls for 2
`(1)/(2)` cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2

2
`(1)/(2)` * 2 = 5 cups of yogurt.

the total of yogurt and oats is
`6(1)/(3)` and we know how much yogurt we have so we subtract that from the total of both.

`6(1)/(3)` - 5 =
`1(1)/(3)`

the oats after doubling were
`1(1)/(3)` cups so u divide it by 2

`1(1)/(3)` / 2 =
`(2)/(3)` before doubling
