Question

GOOD EVENING EVERYONE

CAN YOU SOLVE THIS ​

Answer 1

other parts are like this part

First you have to put × instead of by and then multiple like numerator to numerator, and denominator to denominator..21 doesn't have denominator so we can put 1 as a denominator and we but don't need to write it because we know the answer will be the same number in denominator

so then divide it like I have done in short if we can't divide it like this we can use long method but then the answer will be in mixed fraction .
