Answer:
89 boys to 71 girls, 89:71, or 89/71
Step-by-step explanation:
x+x+36=320
2x+36=320
2x=284
x=142
This means that there are 142 girls.
142+36=178 boys
Simplify the fraction by dividing both numbers by two.
Substitute boys in the equation for b and girls g
b+g=320
b=g+36 (because there are 36 more boys than girls)
g+36+g=320
2g+36=320
2g=320-36
2g=284
g=284/2
g=142
Since b=g+36
b=142+36
b=178
b+g=320
b=g+36 (because there are 36 more boys than girls)
g+36+g=320
2g+36=320
2g=320-36
2g=284
g=284/2
g=142
Since b=g+36
b=142+36
b=178
