Question

an economy package of cups has 920 green cups. If the green cups are 40% of the total package, how many cups are in the package

Answer 1

23000 cups I did this in my head so I think it's right
$\frac{920}{x} = \frac{40}{100}$
You cross multiply
$4x = 92000$
you divide 92,000 by 4 and that gives you 23000
