    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
