Three-fourths of the sixth grade students at ashlee’s school are twelve years old. one-half of the twelve year old students are boys. what fraction of the sixth grade students are twelve year old boys? use numbers to explain your answer.

were is the equation

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
