Question

Two numbers are in the ratio of 5:4, and their sum is 261 then what will be the smaller number?

Answer 1

Answer:

smaller number = 4×29 = 116

Step-by-step explanation:

let the numbers be 5x , 4x

sum of numbers

5x + 4x = 261

9x = 261

x=261 / 9

x =29

Answer 2

$5x + 4x = 261 \\ 9x \: \: \: \: \: \: \: \: \: \: = 261 \\ x \: \: \: \: \: \: \: \: \: \: \: \: = 261 \div 9 \\ x \: \: \: \: \: \: \: \: \: \: \: \: = 29$
now you want to multiply with both
$5x = 5 \times 29 = 145\\ 4x = 4 \times 29\: \: = 116$
by this extra step you can find the number also
