You buy two picture frames that are similar. the ratio of the corresponding side lengths is 4: 5. what is the ratio of the areas?

Let us call the frames A and B

The two sides of A are Ax and Ay

The two sides of B are Bx and By

Bx 4

=

Ax 5

Bx = (4*Ax)/5

As they are similar: By = (4*Ay)/5

Area of A = Ax*Bx

Area of B = Ay*By = (16*Ax*Ay)/25

Area of B 16

=

Area of A 25

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
