Which fraction is between 1/2
and 1?

Step-by-step explanation:

The example fractions of 1/2, 2/3 and 3/4 with common denominators become 6/12, 8/12 and 9/12. The numerator 8 is between 6 and 9, so the fraction you created – 8/12, or 2/3 when simplified – is between the two fractions you started with.

Or think of it like this; A fraction is a value in two parts; each part, the numerator or denominator, is an integer. The numerator is the fraction's top number, while the denominator is its bottom number. Lower-order fractional math like addition and subtraction requires that the denominators of the involved fractions be the same value. When finding a fraction that comes between two others, you ignore normal fractional math in favor of a simpler method.
