Question

divide 3450 among a b c in the ratio 3 5 7

Answer 1

3450 in 3:5:7

3/15 * 3450 = 690

5/15 * 3450 = 1150

7/15 * 3450 = 1610

690:1150:1610

Answer 2

let the unkown ratios be 3x 5x and 7x then

you should add the three ratios. that is 3x+5x+7x=15x

then you should divide 3450 by 15.

you get 230 that means x=230

then 3x=3*230=690

5x=5*230=1150

7x=7*230=1610

therefore the three ratios are 690,1150,1610

to cross examine add the three ratios you get 3450

hope this answer helps you!!!!!!!!!!!
