The digit after (to the right of) the tenths is the hundredths which is a 7 and being 5 or more the tenths round up: 9.074 → 9.1 to the nearest tenth.

7, as when you have a number with any digit of 5 or more in the tenths place, you round up.
To round to the nearest tenth use the hundredth digit to decide to round up or down. The hundredths digit is a 7 so round up. The tenths digit is a 9, so adding 1 gives 10, which means keep the 0 in the tenths column and add 1 to the ones column: 30.97 → 31.0 to the nearest tenth Note that the .0 is normally not written, but as it is written it is significant: it shows the number is accurate to the nearest tenth.
Since the number after the 1 is 7, which is is greater than or equal to 5, you round up the tenths colum from 1 to 2 13.2
The answer is 17. To find this, you look at the tenths column which is 7. If the tenths is 0-4 you round down. If the tenths is 5-9 you round up.
The digit after (to the right of) the tenths is the hundredths which is a 7 and being 5 or more the tenths round up: 9.074 → 9.1 to the nearest tenth.
The tenths place is the number immediately to the right of the decimal point. Remember when rounding to the nearest tenth, your lowest non zero number will be in the tenths place and you will look at the hundredths place to decide whether or not to round up. If the hundredths place is 5 or above, round up in the tenths place. If the hundredths place is 0-4 keep the remaining tenths place number. 7 is in the hundredths place so we will round the tenths place 6 up to a 7. The answer will be .7 or seven tenths.
Look at the tenths digit: if it is 5 or more round up otherwise round down. It is 7, thus round up, thus: 1.7 → 2 rounded to the nearest whole number.

To round a number, the decimal place that you want to round to, needs to be specified. If you want to round to the tenths place or to 1 decimal place, then this number is already there: 7.7 is seven and seven tenths. If you want to round it to zero decimal places, or to the nearest whole number, then look at the tenths place and if it is 0-4 you round down to 7, if it is 5-9 (which it is) you round up to 8.

7, as when you have a number with any digit of 5 or more in the tenths place, you round up.
To round to the nearest tenth use the hundredth digit to decide to round up or down. The hundredths digit is a 7 so round up. The tenths digit is a 9, so adding 1 gives 10, which means keep the 0 in the tenths column and add 1 to the ones column: 30.97 → 31.0 to the nearest tenth Note that the .0 is normally not written, but as it is written it is significant: it shows the number is accurate to the nearest tenth.
Since the number after the 1 is 7, which is is greater than or equal to 5, you round up the tenths colum from 1 to 2 13.2
No you are not able to round like that. You could round it to the nearest whole number which would be 7 or if you were rounding by the decimals tenths place it would be 7.30.
Oh, dude, it's like super easy. So, to round 45.678 to the nearest tenth, you just look at the digit in the hundredths place, which is 7. Since 7 is 5 or greater, you round the tenths place up by 1. So, 45.678 rounded to the nearest tenth is 45.7. Easy peasy, right?
