Question

Jim, Dan and David share some sweets in the ratio 3:1:5. Jim gets 21 sweets. How many more sweets does David get over Dan?

Answer 1

David gets 28 more than Dan

Explanation:

Jim: Dan : David: total

3 : 1 : 5 : 3+1+5 = 9

Jim gets 21

21/3 = 7

Multiply each number by 7

Jim: Dan : David: total

3*7 : 1*7 : 5 *7 : 9*7

21 : 7 : 35 : 63

David has 35 and Dan has 7

35-7 = 28

David gets 28 more than Dan
