Answer 1

Answer:

1. Ans -1/40

2. Ans 2/(-4)

Step-by-step explanation:

1. 7/15+(-8)/25

So, Firstly we have to open the brackets= 7+-8/15+25

So + and - becomes -

So 7-8/15+25

7-8=-1

15+25=40

So ur answer is -1/40

2.(-3)/8+5/(-12)

So, we have to open the brackets = -3+5/8+-12

So + and - becomes -

So, -3+5/8-12

-3+5=2

8-12-4

So, ur answer is 2/-4

Answer 2

Answer:

7/15+(-8)/25

first we need to find lcm of denominators

Lcm of 15 and 25 = 75

35+-(24) upon denominator 75 of both numbers

35-24/75= 11/75 Ans

Step-by-step explanation:

-3/8 +5/-12

lcm= 24

we need to multiply both numerator and denominator both and make the lcm same

-3/8 *3= -9/24

5/-12* 2= -10 /24 we change denominator sign because it never comes negative in ans

-9+-10/24

-19/24 Ans
