If there are 1200 calories in 8 oz of hot fudge, how many calories are in 3 oz?

Answer :

what we have to know is what fracion of 8 oz is 3 oz?

it's [tex] \frac{3}{8} [/tex].


now we multiply this by 1200:

[tex]1200* \frac{3}{8} [/tex].

i'll simplify by dividing by 2:

[tex]600* \frac{3}{4} [/tex].
[tex]300* \frac{3}{2} [/tex].
[tex]150* \frac{3}{1} [/tex].

which is 450. So, the answer is 450 calories!


There are 450 calories for 3 oz.

To solve this, we will use proportionality:

Determine the number of calories per ounce:

1200 calories / 8 oz = 150 calories/oz

Multiply the calories / oz by the number of ounces you have:

150 calories/oz x 3 oz = 450 calories.
