Dinesh painted 2/7of a wall while Rekha painted 3/5of a wall. Who painted moreand by how much?​

Answer»

Answer:

FIRST equalise the denominators and then COMPARE the numerators.The numerator which is greater than other ONE will do more WORK

2/7,3/5

l.c.m of 7 and 5 is 35

2*5/7*5,3*7/5*7

10/35,21/35

10/35<21/35

Hence Rekha painted more by 11/35
