Answer:
This is a proportion problem. A proportion is a statement that two ratios are equal. In this case, we have:
4 cupcakes in 1 box = cupcakes in 4 boxes
To find the missing number, we can use cross-multiplication. We multiply the numerator of the first ratio by the denominator of the second ratio, and then we multiply the denominator of the first ratio by the numerator of the second ratio. We set these two products equal to each other and solve for the missing number.
4 cupcakes in 1 box = cupcakes in 4 boxes
4 x 4 = 1 x cupcakes
16 = cupcakes
Therefore, there are 16 cupcakes in 4 boxes.
