Answer 2

Answer:

Find the least common denominator or LCM of the two denominators:

LCM of 14 and 21 is 42

For the 1st fraction, since 14 × 3 = 42,

314 = 3 × 314 × 3 = 942

Likewise, for the 2nd fraction, since 21 × 2 = 42,

421 = 4 × 221 × 2 = 842

Add the two fractions:

942 + 842 = 9 + 842 = 1742

So, 3/14 + 4/21 = 17/42
