sally was able to eat 58 her lunch John ate 75 lunch who ate

sally was able to eat 5/8 her lunch .John ate 75% lunch. who ate more food

Given, Sally was able to eat 5/8 of her lunch.

and, John ate 75% ,i.e., 75/100 ,i.e., 3/4 of his lunch.

First, we have to find the L.C.M. (Lowest Common Multiple) of the denominators ,i.e., 8 and 4.

L.C.M. of 8 and 4 = 8.

Now, we have to change the denominators to L.C.M. ,i.e., 8.

Then, 5/8 = 5/8 and 3/4 = (3*2)/(4*2) = 6/8.

Therefore, Sally ate 5/8 of her lunch and John ate 6/8 of his lunch.

Hence, John ate more than Sally.
