Question

The sum of three numbers is 98. If the ratio of the first to second is 2 :3 and that of the second to the third is 5 : 8, then the second number is

Answer 1

Give the numbers names, like a, b, and c. Then put them in equations as you go.

Answer 2

or combine the ratios
A B C
2:3 *5
5:8 *3
------
10:15:24

Once you have a combined ratio, you can figure the individual values by proportion.

Example:
4 numbers are in the ratio 2:3:1:4 and the sum of the 4 numbers is 100.
Find the four numbers.

1. Calculate the sum 2+3+1+4=10
2. The corresponding numbers are
100*2/10=20
100*3/10=30
100*1/10=10
100*4/10=40
total =100 ok.
