Answer:
2 cupcakes in second row
(There may be a typo in the question)
Step-by-step explanation:
There are a total of 18 cupcakes
2/3 of these are in the first row
2/3 of 18 = 2/3 x 18 = 12 cupcakes
1/4 in the second row means 1/4 x 18 = 4.5 cupcakes. Since you cannot have half a cupcake, we round down and say there are 4 cupcakes in second row
Remaining cupcakes = 18 - 12 - 4 = 2 cupcakes in third row
