Question

a sum of money is divided among three people in the ratio 15:18:7.find the total sum of money and the largest share,given that the smallest share is $84

Answer 1

well the smallest part in the ratio is 7

so then 7 parts = $84

you can use this to find 1 part of the ratio

\[1 = \frac{84}{7}\]

when you know the value of 1 part you can find the largest share which is 18 parts.

so take the value of 1 part and multiply it by 18.

hope it helps

Answer 2

Can you please further explain it........I mean can you write whole of it in a form of equation for me?

Answer 3

we can change all of them to fractions
\[\frac{ 15 }{40 }, \frac{ 18 }{ 40 }, \frac{ 7 }{40 }\]
the smallest share looks like it is represented by 7/40
therefore
\[\frac{ 7 }{40 }=$84\]
to get largest share:
