Runners in the half marathon entered in three waves. there were 341 runners in the first wave, 295 runners in the second wave, and 316 runners in the third wave. if seven out of eight runners finished the race, how many did not finish? show

190 runners would not have finished the race.

If you add up all the waves, there were 952 total runners.

If 7/8 finished the race, then that means that 1/8 did not finish the race.

Just multiply 1/8 by 952 to get the amount that did not finish.
It would be 190.
