Question

add 8/15 and -2/3 explain​

Answer 1

Step-by-step explanation:

8/15+(-2/3)

= 8/15-2/3

= (8-10)/15. {LCM of 3 and 15}

=-2/15

Answer 2

Answer:

-²/₁₅

Step-by-step explanation:

turn -²/₃ to a like term of ⁸/₁₅. by looking for the L.c.m . after finding the L.C.M, Divide the L.C.M by the current denominator and multiply it by the numerator

it goes as follows

-²/₃ + ⁸/₁₅                              LCM = 15

15 ÷ 3 * -2 = -10

15 ÷ 15 * 8 = 8

So, $\frac{8-10}{15} = -\frac{2}{15}$
