Question

When Gail goes on a hike, she always packs a ratio of 20 protein bars to 15 water

Answer 1

Answer:

4 bars

Step-by-step explanation:

Look at the ratio and cross multiply to solve.

$\frac{15 waters}{20 bars} = \frac{3 waters}{y bars}$

15y = 60

y = 4 bars

Answer 2

Answer:

Gail should pack 4 protein bars if she packs 3 water bottles.

Step-by-step explanation:

First, write out her original ratio; 20:15. Now, you have _:3. Find how to get from 15 to 3. 15 divided by what equals 3? 5. So, to get from 15 to 3, you have to divide by 5. Do the same to 20. 20 divided by 5 equals 4. So, your ratio is 4:3. Gail should pack 4 protein bars if she packs 3 water bottles.
