X/30=15/100. Cross multiply to find x.
I dont know what benchmark means but <em />I hope this works<em>. </em>First, multiply 7 10ths by the denominator of 12. 7/10 *12= 84/120.
Then multiply 5 12ths by 10. 5/12 *10=50/120. So, 7/10 > 5/12
300x .02= 6
6x10=60
Therefore the answer is $360
So to to get 3% of 159 you: 159x0.03=4.77
Kevin would be 24 because 4 times 6 equal to 24
