Answer
23.87 = 23.9
246.91 = 246.9
6341.05 = 6341.1
716.927 = 716.9
Step-by-step explanation
The tenth is the first number after the decimal point.
And in rounding numbers, if the number after the wanted level of precision is less than 5, it is rounded down and if the number is 5 or more, it is rounded up.
So, we go to rounding this
23.87 = 23.9 (7 is greater than 5, so, it is rounded up to turn 8 into 9)
246.91 = 246.9 (1 is less than 5, so, it is rounded down)
6341.05 = 6341.1 (5 is rounded up to make the 0 into a 1)
716.927 = 716.9 (2 is less than 5 and it is rounded down)
Hope this Helps!!!
