Answer 1

Answer:

10/27

Step-by-step explanation:

First we need to  convert hours into minutes.

1 hour = 60 minutes

2 hours= 2 * 60 = 120 minutes

A marathon runner took 2 hours 15 minutes to complete a race.

120 minutes + 15 minutes = 135 mins

During the race he spent  50 minutes in the lead.  

We need to write in fractional form

50/135

The Greatest Common Factor  of 50 and 135 is 5.

We need to divide both numerator and denominator by 5.

Our final answer is 10/27
