Question

In a 720 ml liquid, milk and water have a ratio of 7: 2. How much water is added to make the mixture a ratio of 7:3?​

Answer 1

Answer:

56 ml

Step-by-step explanation:

Ratio is 7:2

Thus, we divide by 9

720/9= 80 ml

Thus, milk= 7x80= 560 ml

water= 2x80= 160 ml

Now, ratio is 7:3

Thus, we divide by 10

720/ 10= 72 ml

Thus, milk= 7x72= 504 ml

water= 3x72= 216 ml

So, we subtract:

216- 160

56 ml should be added

Hope this helps :)
