Question

Usha ate 2/5 of a cake while Vineeta ate 3/7 of the same cake. Who ate more and how much?

Answer 1

Usha ate =2/5
Vineeta ate =3/7
LCM of the denominators is=35
2/5=14/35
3/7=10/35
If you have denominators same then it is easy to find which is greater by comparing the nominators .
Its clear that 2/5 is more because it is same as 14/35.
So usha ate more by 4/35 because  14/35-10/35 =4/35

hope its help you

Answer 2

Hello !

2/5 = Fraction of cake eaten by Usha

3/7 = Fraction of cake eaten by Vineeta

lcm of 5 and 7 = 35

2/5 = 14/35

3/7 = 15/35

14/35 < 15/35

hence ,

Vineeta ate more cake , by 1/35
