Answer:

7.00 hours

Step-by-step explanation:

They already did 4 problems and need to do 18 problems in total.

18 - 4 = 14 problems

2 problems/ per hour

14 problems/ 7 hours

It will take them 7 hours to finish. Since you said "Give your answer to two decimal places." You could write it as 7.00 hours.

Scrat [10]
First off, let's change the mixed fraction to "improper", and do the division then.

\bf \stackrel{mixed}{-5\frac{3}{14}}\implies -\cfrac{5\cdot 14+3}{14}\implies \stackrel{improper}{-\cfrac{73}{14}}\implies -73\div 14\approx -5.21428571
