Question

10. By what number should (1/2)-1 be multiplied so that the product may be equal to
((-4)/7 )-1​

Answer 1

1/2 - 1 * x = -4/7 -1

-1/2 *x = -11/7

x= -11/7 *-2

=22/7

we should multiply it by 22/7 to get -4/7 -1

Answer 2

(1/2) -1 × x =(-4/7) -1

2/1× x = 7/-4 {power is negative so we will reverse the number}

X = 7/-4 ÷ 2/1

X = 7/-4 × 1/2 (divide is change to multiply)

X = -7/8 ANSWER
