Answer 1

Answer:

2/5 hours

Step-by-step explanation:

We can write a proportion to solve

1/10 hour          x hours

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

1/2 package        2 packages

Using cross products

1/10 * 2 = 1/2 x

1/5 = 1/2x

Multiply each side by 2

1/5 * 2 = 1/2x *2

2/5  =x

2/5 hours
