Question

who will give correct answers​

Answer 1

Step-by-step explanation:

ans of q5 = yes because

$1 \times \frac{2}{7} = \frac{9}{7}$

now , on multiplying

$\frac{7}{9} \times \frac{9}{7} = 1$

so

$\frac{7}{9}$

is the multiplicative inverse of

$1 \times \frac{2}{7}$

Answer 2

Step-by-step explanation:

Q5: Yes it is,

why?

• if you solve it you'll get 9/7 so when you divide 1 by 9/7 you'll get 7/9

hence 7/9 is Multiplicative Inverse of 1•2/7
