express 2 1/4 as a single fraction
How many 1/4's in 2?
2%2F%281%2F4%29+=+8
8+%2B+1+=+9
There are 9 1/4's in 1 1/4
------------------------------
How many 1/8's in 3 1/8?
There are 3%2F%281%2F8%29+=+24
24+%2B+1+=+25
There are 25 1/8's in 3 1/8
-----------------------------
What is the difference between 9%2F4
and 25%2F8 ?
How many 1/8's in 9%2F4 ?
%289%2F4%29%2F%281%2F8%29+=+18
-----------------------------
Shelly ran 18%2F8 miles
Lynne 25%2F8 miles
Lynne ran 25%2F8+-+18%2F8+=+7%2F8 miles
further than Shelly
