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:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
