The bright of a model ticket us 4% of the bright of the actual rocket. The model is 1.8 meters high how high us the actual rocket?

Answer 1

is/of = %/100
1.8m/x = 4/100
1.8m = (4/100)(x)
(1.8m)/(4/100) = x
x=45meters
(always remember is/of = %/100)
it comes in handy even in real life while shopping for good sale deals.

Answer 2

How do you define the "bright" of a rocket? Do you mean weight? Breadth?

Why do you call it a ticket?
