b. Solve the system.
c. How many more girls are there than boys?

ratio
a. well...first you divide 1170 by 45(I got 45 by adding the amount of the ratio 23+22) and you get 26.so then you multiply 26 by 23 to get the number of girls. you mulitply 26 by 22 to get the number of boys. so G = 498
b. above
c. there are 26 more girls than boys 
what's the proportion when it's solved, using g/b=22/23?
