tres difficult says that 2630 riders that began last year 3/10 gave up at the end of the race according to the leaflet how many riders finished the event

Question

This is hard difficult and diffent

Answer 1

# riders that started = 2630

# riders who gave up = (3/10) of the # of people who started

                               = (3/10) * 2630 (read of as multiplication)

                               = 3 * 263 (remove common factor of 10 from numerator and denominator)

                               = 789

It is implied that the ones who didn't give up finished.

So, # riders who finished = total - # that gave up

                                     = 2630 - 789

                                     = 1841

Answer 2

Hi Yvette

 

If 3/10 gave up, that means 7/10 got to the end. So multiply:

 

7/10 * 2630

 

You can just write 2630 as 2630/1 and multiply across.

 

7/10 * 2630/1 = 7 * 263 (cancel the 10 with the zero) = 1841.

 

Answer: 1841
