Here's one way
31/4 = 3 + 1/4
= 3*4/4 + 1/4 since 4/4 is the same as 1
= 12/4 + 1/4 and now that the denominators are the same, the numerators can be added to give
= 13/4
3:4
One fourth of 3 is 3/4 = 0.75
3 fourth
3 fourth
51/3 = 16/3 One fourth of that is 4/3 or 11/3
One-fourth times 3 = 3 over 4 = 0.75
It could be -3 or +3.
2 and one fourth divided by 3 = 0.6666666666666666
One fourth of a ruler would be 3 inches. If you mean one fourth of an inch, then it would be between .2 and .3 inches.
3
what is the ratio of 3 to 18
