3 1/9 dived by 2 2/5
cluponka [151]
3 + 1/9 = 27/9 + 1/9 = 28/9

2 + 2/5 = 10/5 + 2/5 = 12/5

So:

[3+(1/9)]/[2+(2/5)]

=(28/9)/(12/5)

=(28/9)*(5/12)

=140/108 = 70/54 = 35/27

BARSIC [14]

$143

First you would have to find out the price that the tent was bumped up to.

52*150%=78

You then add the answer to your original price.

52+78=130

You then have to find the sales tax. You do this by multiplying 10% to your new price.

130*10%=13

You then have to add the sales tax to your number.

130+13=143

$143 is your answer.
