When rounding decimals, you have to look to the furthest number to the right. If the number is higher than five, the number to its right will be rounded up. For example: 10.845 would be rounded up to 10.85. If the number is 45.93, it would be rounded up to 46 since the number nine is higher than five. If the number is 23.24, the number would stay the same. In rounding fractions, if the fraction is greater than one half, it rounds up to the closest whole number. If it isn't, it rounds down. For example, 2 3/8 would round down to 2, while 4 5/8 would round up to 5.
