it would be the third answer choice, when doing this you always make sure that there is multiplication or division you do those first going left to right, even if there is addition first, you still would do either multiplication or division first.

Jerry is a judge. He hears 5 cases in 2 3/8 hours. How many cases does he hear per hour

Serggg [28]

Answer:

Jerry does $2.11$ cases per hour (Rounded to 2 decimal places). As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.

Step-by-step explanation:

to find the number of cases per hour, we have to divide the number of cases by number of hours taken for those cases,

Number of cases per hour = $\frac{5cases}{2\frac{3}{8} hours}$

= $\frac{5}{\frac{19}{8} } \\$ cases per hour

= $\frac{5*8}{19}$ cases per hour

= $\frac{40}{19}$ cases per hour

= $2.11$ cases per hour (Rounded to 2 decimal places)

As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.

27.96 round to the nearest tenth

Serjik [45]

Your tenths place is the 6. If a number is above 5, you round up. and since this number is 96, you would round to 100, but since its a decimal, you round up the actual number to make 28.00. Final answer: 28
