Question

Can anybody help me with this

Answer 1

4) A. 3:1
5) B. 3/4

Step-by-step explanation:
4- In order to get the answer as a whole number you need to multiply each fraction so that it becomes a whole number.
1 1/2 ----> 3/2 * 2 = 6/2 = 3 (water)
1/2 * 2 = 2/2 = 1 (milk)
Since its asking for the water to milk ratio, your answer would be 3:1

5- If you put 3/4 in ratio form it is 3:4 and it can't be divided or multiplied to equal 1/3 or 1:3 whereas the other options can.

Answer 2

For 4, the answer should be 3:1
To find that answer take 1.5 and divide it by 0.5

And for 5, the answer would be 3/4
