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 )
