Question

Three students were given $520 dollars to share in the ratio 0f 2:4:7. How much will each student get

Answer 1

see explanation

Explanation:

sum the parts of the ratio , 2 + 4 + 7 = 13 parts

divide the amount by 13 to find the value of one part of the ratio.

$520 ÷ 13 = $40 ← value of 1 part of ratio , then

2 parts = 2 × $40 = $80

4 parts = 4 × $40 = $160

7 parts = 7 × $40 = $280

Each student receives $80 , $160 , $280

Answer 2

Add up the total parts of the ratio 2+4+7=13 and then divide the amount by the total ratio, 520/13=40 per share, now multiply each share by 40 to get $80:$160:$280
