So last week Paul worked 2.5x this week's hours, so he worked a total of 2.5x15= 37.5 hours last week.
2 1/4 = 2 2/8. So, simply subtract 7 7/8 - 2 2/8 to get your final answer of 5 5/8
They are both equivalent to 1, so they are equal.
The ten thousands place is bigger compared to a digit in the thousands place. Lets say I have 60,000 cookies and you have 6,000 cookies. My number is bigger.
This is a right angle triangle.
So, by Pythagoras theorem,
√(32^2+20^2) = x
or √(1024+400) = x
or √1424 = x
or <em>37.74 = x</em>
