There has to be a decimal in order to round to the "hundreths" place. I'm assuming you meant ".091" in which case you would look at the hundreths column, which is a 9. Then to round, you look at the number to the right of the number you're rounding, if it's greater than 5 you round up, less than 5 you stay the same. Since the number to the right is 1, your final answer is ".09"

3/16 x124=23.25
7/16 x124=54.25
1/16 x124=7.75
It’s 3/6 but you simplify it to 1/2
