What ratio is equal to 1/3?
3:1
6:9
20:80
21:63
Thank you very much!
You're very welcome.
Well, let's do some ratio-fun math, shall we? The ratio that equals 1/3 is 3:1. But don't worry, the other options aren't useless either! They just want to play along. 6:9 is a sneaky way of saying 2:3, which isn't equal to 1/3. And as for 20:80, that's just saying 1:4, which is a bit too much for our one-third equation. Finally, 21:63 is a clever way to express 1:3, which is exactly what we're looking for! So, in short, 3:1 or 21:63 are the ratios that equal 1/3. Keep the fractions entertained, my friend!
To find the ratio equal to 1/3, we need to find a ratio where the numerator is one-third of the denominator.
Let's check the given options one by one:
3:1 - Here, the numerator is three times the denominator, so it is not equal to 1/3.
6:9 - Here, if we simplify the ratio, we get 2:3, so it is not equal to 1/3.
20:80 - Here, if we simplify the ratio, we get 1:4, so it is not equal to 1/3.
21:63 - Here, if we simplify the ratio, we get 1:3, which is equal to 1/3.
Thus, the ratio 21:63 is equal to 1/3.
It can't be 3:1
6:9 = 6/9 = 2/3
Which of the other two is equal to 1/3?
21:63
Right!
The fraction 21/63 reduces to 1/3.
