Answer:
1/3
Explanation:
For the 1st fraction, since 4 × 3 = 12,
3 /4 = 3 × 3/ 4 × 3 = 9/ 12
Likewise, for the 2nd fraction, since 12 × 1 = 12,
5 /12 = 5 × 1 /12 × 1 = 5 /12
Subtract the two fractions: 9 /12 - 5 /12 = 9 - 5 /12 = 4 /12
So next you simplify the answer how many 4 go in 4 and how many go in 12 the simplified answer is the answer is 1/3
Hope this helps
