Brainliest answer asapdavid, egil and frances share money in the ratio 2: 7: 9. explain why frances will always get half of the money they share.

answer: answer 80$

step-by-step explanation: step-by-step explanation:

we have been given that david, egil and frances share money in the ratio 2: 7: 9.

let 2x, 7x and 9x be the amounts of money that david, agil and frances get respectively.  

we are told that frances gets $80 more than david. so we can write this information in an equation as:

9x=2x+80

now let us solve for x.

9x-2x=80

7x=80

x=\frac{80}{7}

now let us substitute x=\frac{80}{7} in 7x (amount of money that egil gets).

\text{ amount of money that egil will get}=7\cdot \frac{80}{7}

upon cancelling out 7 from numerator and denominator we will get,

\text{ amount of money that egil will get}=80  

therefore, egil will get $80.
