ratio of 3/2 boys and girls 12 boys in class how must girls is
Please proofread and clarify your problem. It makes no sense the way you posted it.
apparently there are 3 boys for every 2 girls
given 12 boys, that makes 3*4 boys
so, there are 2*4 = 8 girls
surely the problem was not expressed in such vague and inaccurate language. Why not just copy it as it was written?
There were 12 boys and 18 girls in a class. Then, 3 more boys joined
the class and 2 girls left. What is the ratio of the number of boys to
the number of girls in the class now?
To determine the number of girls in the class, we need to use the ratio of boys to girls provided.
The given ratio is 3/2, which means that for every 3 boys, there are 2 girls.
Currently, we know that there are 12 boys in the class.
To find the number of girls, we can set up a proportion:
(Number of boys) / (Number of girls) = (Ratio of boys to girls)
Plugging in the known values:
12 / (Number of girls) = 3 / 2
To solve for the number of girls, we can cross-multiply:
12 * 2 = 3 * (Number of girls)
24 = 3 * (Number of girls)
Divide both sides of the equation by 3:
24 / 3 = (Number of girls)
8 = (Number of girls)
Therefore, there are 8 girls in the class.
