Answer:

1/3

Step-by-step 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
