the ratio of boys to girls would be 24:18 or 24/18 or 24 to 18 or "for every 24 boys there will be 18 girls".
a proportion equation would be b/g = 24/18
b = number of boys
g = number of girls
this would read as "the ratio of the nmber of boys to number of girls is equal to 24/18.
you would solve a problen involving this ratio as follows:
if the ratio of boys to girls is 24 to 18, and you have 90 girls, then how many boys do you have.
you would then set up the equation as follows:
24/18 = x/90
this is a proportion equation that says that the ratio of x/90 must be the same as the ratio of 24/18.
you sould multiply both sides of this equation by 90 to get:
24/18 * 90 = x
you would then solve for x to get x = 120.
the ratio of 24/18 is the same as the ratio of 120/90
in fact, 24/18 * 5/5 = 120/90, confirming the ratios are the same.
if the ratios are the same, then the cross product is the same.
the ratio of 24/18 is the same as the ratio of 120/90 because 24*90 = 18*120.
they are both equal to 2160.
