Ineed to rounding decimals numbers

So say the value of a decimal is 3.495 and the question asks you to round to the nearest 10th. you look at the number in front of the number in the 10ths place and round it either up or down based on that. If the number is 5 or above, you round it up. If it's below 5 you round the number in the 10ths place down.

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )

I’m pretty sure it’s i think : /
