Step-by-step explanation:
Ridhima solved 1/7 part of an exercise while rakhi solved 3/5 of it. who solved greater part ? By how much?
part of exercise solved by Ridhima = 1/7
part of exercise solved by Rakhi = 3/5
comparing the exercises done by both
Ridhima. Rakhi
1/7 3/5
By cross multiplication
1×5 ______ 3×7
5. < 21
Rakhi has solved greater part.
How much more Rakhi Solved = 3/5 - 1/7
Taking L.C.M of 5 and 7 = 35
→ 3/5 × 7/7 - 1/7 × 5/5
→ 21/35 - 5/35
→ 17/35 ans
