Answer:
a) 30/24
Explanation:
To work this out, we must simplify all the other fraction to see which one leaves us with 5/4. Hence:
a) 30/24
= 5/4 ← dividing both numbers by the highest common factor, 6
b) 30/20
= 3/2 ← dividing both numbers by the highest common factor, 10
c) 24/30
= 4/5 ← dividing both numbers by the highest common factor, 6
d) 20/30
= 2/3 ← dividing both numbers by the highest common factor, 10
Hence, we can see that a) is the correct answer, as when simplified it equates to 5/4, same as the original ratio. Hope that helps!
