-3/10+-1/5 -18/15 x 5/-4
3/8 divided by -1/4
Please give a little bit long answer but not a single answer

Step-by-step explanation:

-3/10+ -1/5

find the common denominator. on that case its 10

10 into 10 that's 1 so 3 remain 3 . then 5 into 10 its 2 so 1×2=2

-3/10 + -2/10

-3+-2

-3-2= -5

-5/10= -1/2

Ans is -1/2

-18/15 ×5/-4

you cross multiply. 5into 15 to get a denominator 3 then -4/2=-2 denominator. -18/2=-9. you multiply 3×-2=-6 then we are left with

-9/-6= -3/-2=1 and half

Ans is 1 1/2 (one and 1 half ).

3/8÷ -1/4

you spin -1/4 to -4/1 inorder to change the sign to a multiplication sign.

3/8 × -4/1 1

cross multiply to get -3/2

-3/2 = - 1 1/2

Ans : 1 1/2 ( one and one half )
