Question at the football game, 8 out of every 20 spectators were girls. there were a total of 1560 spectators at the game. how many of the spectators were girls?

8/20 spectators are girls
8/20 = 0.4

1560 x 0.4 = 624

and therefore 624 of the spectators were girls

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
