Question

$(i) 4 \ 9 and 44 \ 99 (ii) 7 \ -3 and 35\ - 15 (iii) - 3 \ 5 and - 12 \ 20$
in each of the following cases, show that the rational numbers are equivalent. ​

Answer 1

(44/99)/ (11/11) = 4/9

When we multiply 4/9 with 11/11 we get 44/99

(35/-15)/(5/5) = 7/-3

When we multiply 7/-3 with 5/5 we get 35/-15

(-12/20)/(4/4)= -3/5

When we multiply 3/5 with 4/4 we get -12/20

hope it helps you
