Answer:

37.5% are male

62.5% are female

Step-by-step explanation:

in total 120 teachers (45 male+75 female)

therefore:

for male

120 - 100%

45 - x%  (we need to find x)

by using the butterfly method (or cross multiply) we get:

120x=100*45

x=4500/120=37.5% (male teachers)

we do the same for female but instead of using 45 we will use 75(the quantity of female theachers in school)

120x=100*75

x=7500/120=62.5%

SOMEONE PLEASE I NEED HELP!!!!!!!
Genrish500 [490]

Answer:

1 1/2 cups

Step-by-step explanation:

2/3 cup of almonds = 4 cups of trail mix

4 cups of trail mix = 2/3 cup of almond

4 cups of trail mix = 2/3 cup of almond

1 cup of trail mix = 2/3 ÷ 4 = 1/6 cup of almond

1 cup of trail mix = 1/6 cup of almond

9 cups of trail mix = 1/6 x 9 = 3/2 cup of almond

3/2 cups = 1 1/2 cups
