Plz me do this math problem. it says "my brother nathan is 15 years old and my uncle is 40 years old. how many years will it take for my brother nathan to reach the age of 40" than it says "write an equation and solve the problem show your work"

25

Step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
