A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How many solutions are possible for this situation? 1) Infinitely many solutions exist because the two situations describe the same line.
2) Exactly one solution exists because the situation describes two lines that have different slopes and different y-intercepts.
3) No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
4) Exactly one solution exists because the situation describes two lines with different slopes and the same y-intercept.

note that 36/9 is also equal to 4.

thus we look for fractions that is also equal to 4.

the denominator of 4 is 1 (any number divided by 1 is itself). thus we only multiply the numerator and denominator by the same number to get an equivalent fraction. for instance, let's multiply 4/1 by 2:

4/1 * 2/2 = (4*2)/(1*2) = 8/2

thus 8/2 is an equivalent fraction.

let's try multiplying by 3:

4/1 * 3/3 = (4*3)/(1*3) = 12/3

thus 12/3 is also another equivalent fraction.

multiplying by 4,

4/1 * 4/4 = (4*4)/(1*4) = 16/4

16/4 is another equivalent fraction.

hope this helps~ :)
