Question

9.9g of sugar is needed for every cake made. How much sugar is needed for 8 cakes?

Answer 1

See answer below

Explanation:

Hi there,

Get started by developing a relationship between the amount of sugar for 1 cake. We can use dimensional analysis to solve this.

`(9.9 \ g \ sugar)/(1 \ cake)`

Now, we know that we need 8 cakes. We put 1 cake on the bottom of the fraction so that it cancels out with the 8 cakes unit:

`(9.9 \ g \ sugar)/(1 \ cake)`
`* \ 8 \ cake = 9.9 g \ sugar * 8 = 79.2 g \ sugar`

thanks,

Answer 2

79.2 g of sugar is needed.

Explanation:

9.9 times 8 is 79.2.

You can prove this by dividing 79.2 by 8 and you will get 9.9 as the answer.
