The correct answer is 50.3
It is 12.9 when rounded to one decimal place.
It is 4.8 when rounded to one decimal place.
0.9
141.4 (because 7 > 4, so you round up)
It is 27.6 since 4 the 4 after the 1st six is smaller than five
To answer this we need to look at the 2nd decimal place. if the 2nd decimal place is 5 or larger then we add 1 to the 1st decimal place, if it is 4 or less than we do not add 1 and just truncate the rest of the digits. Examples: 12.45 = 12.5 (because 5 needs to be rounded up) 12.31 = 12.3 (because 3 is less than 5) etc So, 342.3846 = 342.4 since 8 is larger than 4
The second decimal place is 5 or more, so the first decimal place increases by 1.69.6
The ones place, since it is the 1st place past the decimal place.
It is 8.0 rounded to one decimal point.
You would round it up to 68.6
To round 42.5 to 1 decimal place, you look at the digit immediately to the right of the decimal point, which is 5. Since 5 is 5 or greater, you round the digit in the 1st decimal place up by 1. Therefore, 42.5 rounded to 1 decimal place is 42.6.
7.4 When we refer to something as a tenth we mean to the 1st decimal place.
