Answer 1

(-5/7×3) ÷ (-5/49)

-5/21 × 49/-5

7/3

Answer 2

Step-by-step explanation:

you have first cross multiply the number in the bracket. those numbers that cannot be cross multiplied. then just multiply the number other number infront of it, like in the first bracket 3 and 9 were cross multiplied and then in the numerator 1 was left so 1 multiply by -5 became -5 and in denominator 7 multiply by 3 became 21.

do the same in other bracket.

then, you got -5/21 from first bracket and -5/49 from other. now the divide sign in between will be replaced with multiply sign and in the 2nd value denominator will change with numerator so it will become 49/-5.
