Answer 2

Answer: 7/10

Step-by-step explanation:

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

LCM of 10 and 5 is 10

For the 1st fraction, since 10 × 1 = 10,

3/10 =

3 × 1/10 × 1 = 3/10

Likewise, for the 2nd fraction, since 5 × 2 = 10,

2/5 = 2 × 2/5 × 2 = 4/10

Add the two fractions:

3/10+ 4/10 = 3 + 4/10 = 7/10

So, 3/10 + 2/5 = 7/10
