Add:

-3/5+ (8/35)

You try getting the equivalent fractions with the same denominators. That's your first step.

-3/35 + 8/35= 5/35= 1/7

You didn't get the equivalent fraction.

You need to multiply the numerator and denominator by the same number.

3/5 = ? /35

To add fractions, you need to have a common denominator. In this case, the common denominator is 35 because both fractions have 35 as a denominator.

To add fractions with the same denominator, you simply add the numerators and keep the denominator the same.

So, for -3/5 + 8/35, we can rewrite -3/5 as -21/35 (multiplied both numerator and denominator by 7 to get the denominator 35), and then we can add the numerators:

-21/35 + 8/35 = (-21 + 8)/35 = -13/35

Therefore, the sum of -3/5 + 8/35 is -13/35.
