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?

8 donuts

Step-by-step 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

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
