598.61 rounded to the nearest tenth is 598.60 I got the answer by rounding ;P
jk
You just have to look at the tenths place (the place your rounding to) which is .6 The look to the number next to it on the right (.01) If that number on the right is 4 or less, the number youre rounding to stays the same (but all the numbers to the right of it turn into zeros.) If the number to the right is 5 or more, than add 1 to the number your rounding to. But here the number to the right is less than 4 so the answer is 598.60.
Multiply 5 with y equals 5y the divide 30 by 5 and multiply your answers
