Answer:6/7,54/63

6/7

6×9=54

7×9=63

So.these both are equivalent

Answer:Step-by-step explanation:(i) LCM of the denominators 7 and 63 is 63. Then change both the denominators to 63. To change 1st no. you need to multiply the denominator by 9 (because 7*9=63) if we multiply the denominator with 9 we need to multiply the numerator also. Therefore, the fraction 6/7 becomes 54/63.

you can do the rest in the same way hope this helps if you want me to send more detailed explanation pls reply
