Answer: a)
Explanation:
a) 4\12 b) 1\4 c) 3\4 d) 3\3
If you’re trying to find 1\3, then you can instantly rule out 3\3.
Let’s find a common denominator (bottom number). This part is quite easy. It would be 12.
To make the 3 into a 12, you have to times it by 4, therefore you have to times the numerator (top number) by 4 as well, making 4\12. This is answer a).
To check the answer, let’s find b) and c) as the denominator 12.
They are both 4, so you would times by 3, making b) 3\12 and c) 9\12. They aren’t 4\12, so we got the answer right.
