84.7g of sugar is needed to make 11 cakes. How much sugar is needed for 5 cakes

38.5 grams of sugar for 5 cakes

Step-by-step explanation:

Set up a ratio of grams to cakes

84.7g:11

How much for 1 cake(unit rate because you want sugar over cakes)?

Just divide by 11.

7.7g:1

But you need 5 cakes so multiply by 5

38.5g:5

Step-by-step explanation:

First divide 84.7 and 11 which is 7.7

So there is 7.7g of sugar in one cake.

Next multiply 7.7 by 5 which is 38.5

Therefore you need 38.5g of sugar for 5 cakes

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
