# if 3/4 equals 120 what does 4/4 equal?

4/4 would equal 160.

Use proportions to solve this answer, like John McCann did above.

(3/4)/120 = (4/4)/x

We use x because 4/4 isn't given a number, while 3/4 is.

(3/4)/120 = 1/x

3/4 = 120 * (1/x)

3/4 = 120/x

(3/4) * x = (120/x) * x

3x/4 = 120

(3x/4) * 4 = 120 * 4

3x = 480

3x/3 = 480/3

x = 160 <--- 4/4 would equal to 160 is 3/4 was equal to 120.

Showing how you came to that conclusion would be super helpful for the person who asked this question. Don't be afraid to show off your mad math skills!

3/4//100 = 4/4//X

(3/4)X = 100

X = 133.3

======Do it with decimals and see.

Indeed! I must of had that first wrong answer in my head when I set up the equality.

Answer the question to get it to the questioner correctly.

Do you ever get a chance to correct your math teacher?

Actually, yes, very few times does my math teacher make a mistake when trying to explain how to solve certain problems. And I do usually catch them right on the spot.
John McCann commented
College math teachers can be extremely correctable for some reason. Perhaps publish or perish has a hand in this, or too many classes to teach could be it.

We are given that 3/4 = 120                      ...(1)

Now let 4/4 = x                  ...(2)

Dividing equation 1 by equation 2,

(3/4) / (4/4) = (120) / x

Now doing a cross multiplication, we get,

3/4 *x = 120 *(4/4)

So, 3x/4 = 120

Now, Multiplying by 4 on both sides of the equation, we get,

3x = 120*4

Dividing by 3 on both sides, we get,

x = 120*4/3 = 40*4 = 160

So, x = 160 = 4/4
