Studdy Solution

STEP 1

Assumptions1. We are rounding numbers to the nearest tenth, whole number, or other specified place value. . When rounding, if the digit to the right of the place value we are rounding to is5 or greater, we round up. If it is less than5, we round down.

STEP 2

First, let's answer question1. To round74.58 to the nearest tenth, we look at the digit in the hundredths place.

STEP 3

The digit in the hundredths place is8, which is greater than5. Therefore, we round up the digit in the tenths place.

STEP 4

So,74.58 rounded to the nearest tenth is74.6.

STEP 5

For question2, we are rounding to the nearest whole number. We look at the digit in the tenths place.

STEP 6

The digit in the tenths place is8, which is greater than5. Therefore, we round up the digit in the ones place.

STEP 7

So, George will be charged for41 miles.

STEP 8

For question3, the number16.5 is already rounded to the nearest tenth.

STEP 9

For question4, the number56. is already rounded to the nearest tenth.

STEP 10

For question5, to round.32 to the nearest tenth, we look at the digit in the hundredths place.

STEP 11

The digit in the hundredths place is, which is less than5. Therefore, we round down the digit in the tenths place.

STEP 12

So,.32 rounded to the nearest tenth is..

STEP 13

For question6, to round42.78 to the nearest tenth, we look at the digit in the hundredths place.

STEP 14

The digit in the hundredths place is8, which is greater than. Therefore, we round up the digit in the tenths place.

STEP 15

So,42.78 rounded to the nearest tenth is42.8.

STEP 16

For question, to round.652 to the nearest hundredth, we look at the digit in the thousandths place.

STEP 17

The digit in the thousandths place is2, which is less than5. Therefore, we round down the digit in the hundredths place.

STEP 18

So,.652 rounded to the nearest hundredth is.65.

STEP 19

For question8, the number582.04 is already rounded to the nearest hundredth.

STEP 20

For question9, to round $80,547.645 to the nearest hundredth, we look at the digit in the thousandths place.

STEP 21

The digit in the thousandths place is5, which is equal to5. Therefore, we round up the digit in the hundredths place.

STEP 22

So, 80,547.645roundedtothenearesthundredthis80,547.645 rounded to the nearest hundredth is 80,547.65.

STEP 23

For question10, to round $80,547.645 to the nearest tenth, we look at the digit in the hundredths place.

STEP 24

The digit in the hundredths place is4, which is less than. Therefore, we round down the digit in the tenths place.

STEP 25

So, 80,547.645roundedtothenearesttenthis80,547.645 rounded to the nearest tenth is 80,547..
