Question 5

What amount represents the best rounding of 7.68 mL?

Accepted Answer

Common syringes,medication spoons,and medication cups are only calibrated to a tenth of an mL.If a calculation goes out to more than one place past the decimal (is uneven),round up or down to the next tenth of a place depending on whether the end number is below 5 or is 5 or above.In this case,the end decimal number is 8,which is higher than 5.So,round 7.68 up to 7.7.

Accepted Answer

Of these fractions,4/8 can be further reduced to 1/4,2/20 can be further reduced to 1/10,5/15 can be further reduced to 1/3.Only 3/17 cannot be further reduced.

Question 17

What is 12% of 60?

Accepted Answer

To get the percent of a number,multiply the number by the percentage you want.In this case,60 F1F1F1S1F1F1F10 0.12 = 7.2.Remember that percent is based on 100.So,12% is represented by the decimal 0.12.
