20 30

explain briefly pls​

Answer 1

Answer:

1/12

Explanation:

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

LCM of 30 and 20 is 60

For the 1st fraction, since 30 × 2 = 60,

130 = 1 × 230 × 2 = 260

Likewise, for the 2nd fraction, since 20 × 3 = 60,

120 = 1 × 320 × 3 = 360

Add the two fractions:

260 + 360 = 2 + 360 = 560

5/60 simplified gives 112

So, 1/30 + 1/20 = 1/12
