The first thing you do is to find the lowest common multiple of 5 and 7.What you do on the bottom, you must do on the top 25/35 / 28/35. The answer is 25/28. Sara ran 25/28 of the total distance around the track.
If you write a number over another number, it's called a FRACTION
it is 24.75
I used a long division method to find the value of 50
06087
this would look like this: 0.0000001^10
If we were to do 0.0000001*0.0000001 it would be 0.00000000000010
We doubled the zeroes and moved the one up. Continue on until you reach the tenth power.
