Answer 1

Answer:

A.)10/117

B). 38/57

C.) 1/55

Step-by-step explanation:

A). 2/9*5/13 (there is a multiplication)

(multiply numerator by numerator and denominator by denominator if any number is not divisible by any number.)

So,

2*5=10

9*13=117

Answer: 10/117

B). 7/19*-38/21

(multiplying after cutting the divisible numbers)

7 cutted with 21 then our equation takes a change

1/19*-38/3

(multiplying numerator by numerator denominator by denominator)

1*-38= -38

19*3= 57

Answer: 38/57

C). - 2/77*35/-50

(first cutting minus signs with both the number then multiplying after cutting the divisible numbers)

So,

(now, our equation changes)

1/11*1/5

1*1=1

11*5=55

Answer=1/55
