Three of fifteen pieces of gum are purple. write the fraction and the % of the gum that is purple.

1/5 of the gum is purple

20% is purple

Step-by-step explanation:

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

$15 each

step-by-step explanation:

$45/3 children= $15 each
