Question

simplify (3/5 multiply -10/9) + (-4/5 multiply 1/-8) -(2/5 multiply -15/16​

Answer 1

Step-by-step explanation:

3/5×-10/9= -2/3(cancelling 5 with -10 and 3 with 9)

-4/5×1/-8= -1/-10(cancelling 4 with 8)

-2/5×-15/16= 3/8(cancelling 5 with 15 and 2 with 16 ,and we didn't put + sign as there were 2 - with make +)

-2 + 1 - 3 = -20/30 + (3/30) - 3/8 = -17/30

3 10 8

-17/30 -3/8= -136/240 - 90/240 = -226/240 = 0.925
