Answer 2

$\huge\bf\underline{Answer}$

4)The myltiplicative inverse of 72 is $\frac{1}{72}$

We have to take just reciprocal of a number Hence it is called as multplicative inverse of a number

option (c)

______________________________________________________

5) 9y7 is a multiple of 3 Y=?

We have to substuite value of y from given options

a) 947 =It is not a multiple of 3

b) 937 = It is not a multiple of 3

c) 967=It is not multiple of 3

d) 927 It is a multiple

957 It Multiple of 3

987 It is Multiple of 3

Hence option( d)
