Answer:
6 : 1
12 : 2
Step-by-step explanation:
We want to find ratios which are equivalent to 24 : 4. Equivalent means that they area they same. We will use process of elimination to work out the answer so lets begin,
1st option
24 : 4 simplifies down to 6 : 1 if we half once and then half again
24 : 4
12 : 2
6 : 1
So 6 : 1 is an equivalent ratio
2nd option
24 : 4 simplifies down to 6 : 1 if we half once and then half again but 8 : 4 simplifies to 2 : 1 so 8 : 4 is not equivalent ratio
3rd option
24 : 2 simplifies down to 6 : 1 if we half once and then half again
24 : 4
12 : 2
So 12 : 2 is an equivalent ratio
4th option
15 : 3 simplifies down to 5 : 1 so 15 : 3 is not an equivalent ratio
