Answer:
56
Step-by-step explanation:
The ratio is 5 to 2, and we must keep it this way.
For example, if he had 10 regular sodas then the ratio would be 10:4.
If something happens to one side of this ratio, it needs to happen to the other so it remains balanced.
We need to find out how 5 got to 140. To find out, simply divide 140 by 5.
140 divided by 5 = 28
So, 5 was multiplied by 28 to get to 140.
Now, we need to multiply the 2 by 28 as well so it remains balanced.
2 x 28 = 56.
So, there are 56 diet sodas.
