1. ## help with word problem (equation setup)

The ratio of two numbers in 5/4 and the first number is 7 more than the second number. to determine each of these numbers let x be the first number.
a)since the first number is 7 more than the second number and since the first number is x, what is the second number?
b)write a formula for the fraction (ratio) consisting the first number divided by the second number.
c) write an equation that says that this fraction (ratio) is 5/4.
d) solve the equaton
e) what are the two numbers

Well, if the smaller number is x and the other number is x+7, I can set up the following ratio

$\overbrace{\frac{x+7}{x}}^\text{first number over second number}=\frac{5}{4}$

3. how would you solve the equation?

Cross multiply, move x terms to one side of the eqution and constants to the other, combine like terms, and then divide each side by the coefficient of the variable.
