L = A/W
L = 72a³b⁴ / <span>6a²b
L = 12 a b</span>³
So the are of the cup is 3*3 or 9
the area of the cup space is 10*10 or 100
we see how many times 9 goes into 100
100/9=11.1111
but we cant fit part of a cup so we round down and get
can fit 11 cups
\begin{lgathered}18 \times 15 = 270 \\ 270 \div 7 = 38.56 \\ 38\end{lgathered}
18×15=270
270÷7=38.56
38 aples
1/3 = 4/12
1/4 = 3/12
4/12 + 3/12 = 7/12
