Your cousin gave you 27 dollars with which to buy a present. this covered 9/10 of the cost. how much did the present cost
2 answers:
The other answer is working the wrong way.
27 dollars is ONLY 9/10 of the cost.
Which means we have to do the following:
27/9=3
3*10 = 30
The total cost of the present, was 30 dollars.
27/10 is 2.7
2.7*9 gets you $24.3
