Question

Can you guys help me? :-(

Answer 1

2/5 + 5/10 = 9/10

Explanation:

Turn 2/5 into 4/10 to make the two fractions' denominators the same by multiplying 2 × 2 =4 and 5 × 2 = 10. Then add 4/10 + 5/10 to get 9/10.

Answer 2

`(9)/(10)`

Explanation:

Find the LCD because like last time, you cannot add or subtract fractions with different denominators.

LCD = 10

Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.

`(2 * 2)/(5 * 2)`

`(4)/(10)`

`(4 + 5)/(10)`

`= (9)/(10)`
