I need to know how to solve more problems like this

We need to find how much she makes an hour so 27 divided by 3 is 9 so she makes 9 dollars an hour so then we need to multiply that by the 4 hours
4 x 9 = 36
So she made 36 dollars in 4 hours
I think this is correct hopes it helped :)

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 : )
