Question

2/3 cup of oatmeal is needed to make 10 granola bars. how many such granola bars can be made with 20 cups ofoatmeal

Answer 1

Answer:

Hi Gracie;

(2/3) cup=10 bars

[(20) cups]/[(2/3) cups]=(x bars)/(10 bars)

Let's first notice that on the left side, the unit of cups is in the numerator and denominator. These cancel.

Let's next notice that on the right side, the unit of bars is in the numerator and denominator. These cancel.

[(20) cups]/[(2/3) cups]=(x bars)/(10 bars)

(20)/(2/3)=x/10

This can also be written as....

(3/2)(20)=x/10

60/2=x/10

30=x/10

Let's multiply both sides by 10...

30(10)=(x/10)(10)

300=x

Twenty cups of oatmeal would make 300 granola bars.
