The sum of three numbers is 116. the ratio of second to the third is 9 : 16 and the first to the third is 1 : 4. the second number is
Answers
Ratio of second : third = 9 : 16
Ratio of first : third : 1 : 4
................................................................................................................
STEP 1: Make the third's ratio the same:
Since both ratio has third, we will make both the third's ratio the same
Ratio of second : third = 9 : 16
Ratio of first : third : 1 : 4
multiply by 4 :
Ratio of first : third : 4 : 16
................................................................................................................
STEP 2: Put the ratio together:
first : second : third = 4 : 9 : 16
................................................................................................................
STEP 3: Find x:
Let x be the constant ratio.
The sum of these 3 numbers is 116
4x + 9x + 16x = 116
29x = 116
x = 4

STEP 4: Find the second number:
second number = 9x = 9(4) = 36
