What is the ratio of boys to girls in ms. smith's class is 3 to 4 if there are 12 boys how many total students are there?

3 boys to 4 girls. You know you have 12 boys/ ?girls. Do the boys first. 12 divides into 3 4 times, so you would multiply girls by the same amount.

3 x 4 = 12

4 x 4 = 16

So, you would have 12 boys/ 16 girls. Ratio 12 to 16 or 12 : 16

Hope this helps you. :)

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

probably .5

i can on others if necessary.
