There are 8 runners in a race.
The 4 fastest runners will win trophies.
Halfway through the race, 2 of the
runners drop out of the race. What
fraction of the remaining runners will win
a trophy?

Respuesta :

at first = 8 runners
Halfway, 2 dropped out, remaining 8 - 2 = 6 runners
4 fastest runners win
Fraction = 4/6 = 2/3
4/6 or 2/3 of the remaining runners will win a trophy. 
There are 6 runners left, and 4 will win a trophy. 4/6 simplifies to 2/3
