Question

The nutrition fact on a particular snack food states that 40% of calories come from fat. If 20 of the total calories come from fat, how many total calories are in the food.

Answer 1

The total calories in the food is 50.

Explanation:

Given,

Calories coming from fat = 20

In percentile calories coming from fat = 40%

Solution,

Let the total calories in the food be 'x'.

And given that 40% of the total calories are coming from fat, which is 20.

That means x multiplied with 40% is equal to 20.

So framing the above sentence in equation form, we get;

`x*40\%=20`

Now we have to remove the percentile.

For this we have to divide 40 by 100, then we get;

`x*(40)/(100)=20\\`

Multiplying by 100 on both side, we get;

`x*40=20*100\\\\x=(20*100)/(40)\\\\x=50`

Hence The total calories in the food is 50.
