Question

Erin has 1/2 a pound of dough to make donuts. If 1/8 of a pound makes 2 donuts, how many can 1/2 a pound of dough make?

Answer 1

8 donuts

Explanation:

We can use a ratio to solve

1/8 lbs 1/2 lbs

-------------- = --------------

2 donuts x donuts

Using cross products

1/8 * x = 2 * 1/2

1/8x = 1

Multiply each side by 8

1/8x *8 = 1*8

x = 8
