Question

Round these numbers to the nearest tenth. a) 74.3472 b) 98.759

Answer 1

Answer:

a) 74.3

b) 98.8

Step-by-step explanation:

The tenth decimal place is the first place immediately to the right of the decimal point. When rounding, you first need to look at the number to the right of the place you wish to find. If the number in this spot is 5 - 9, round the number in the tenth decimal place up one unit. If the number is 0 - 4, keep the number in the tenth decimal place the same. Finally, remove all of the numbers to the right of the tenth decimal place.

a) 74.3472

        ^ tenth

The next number to the right (4) is not big enough to round up

a) 74.3

b) 98.759

Answer 2

Answer:

Go to the tenths place, and check the hundredths spot. If the number in the hundredths is less than five, leave the tenths place alone. If it is greater than five, round the tenths place up.
