What is number 5? I wanna did I do number 4 rt?

5) 1.5 : 7

Step-by-step explanation:

I think for 4) you need only one ratio, for example

The ratio of lemon to sugar is

1 : 1,5

This is the same lik 2:3, or any other you wrote. So it is enough to write just one ratio.

5) also one ratio is enough, becuse all other are the same.

The ratio of cups od sugar to cups of water is 1.5 : 7.

step-by-step explanation:

30% of 170 is 51. 170+51=221
