B. -4/3

C. -3/4

D. -25/27

Answers

Answer 1
Answer: -(5)/(6) ÷ (9)/(10)

First, apply the rule (easiest way if you have learned it): a ÷ (b)/(c) = a × (c)/(b)
- (5)/(6) × (10)/(9)
Second, apply the last rule: (a)/(b) × (c)/(d) = (ac)/(bd)
- (5*10)/(6*9)
Third, multiply 5 × 10 to get 50.
- (50)/(6*9)
Fourth, multiply 6 × 9 to get 54. 
-(50)/(54)
Fifth, find the GCF of 50 and 54.
The GCF should be 2.
Sixth, divide the numerator by the GCF. 
50 ÷ 2 = 25
Seventh, divide the denominator by the GCF.
54 ÷ 2 = 27
Eighth, now put 25 and 27 together to get the simplified fraction.
- (25)/(27)

Answer as fraction: -(25)/(27)
Answer as decimal: 0.9259
