Changing them to same denominator and then to mixed number makes it easier subtract.
23 1/4 - 1 1/2
= 23 1/4 - 1 2/4 << change them to same denominator
= 93/4 - 6/4 << now to mixed fraction
= 87/4 << subtract them
= 21 3/4 (Answer)
ps. 21 3/4 is same as 21.75 << 3/4 * 100 = 75
----------------------------
Another method. Could be a little confusing if you are new to whole/mixed numbers and fractions... you could ask someone else to explain this to you.
23 1/4 - 1 1/2
= 23 1/4 - 1 2/4
= 22 (4/4 + 1/4) - 1 2/4 <<<< [The confusing part.. but soon you should understand it.]
= 22 5/4 - 1 2/4 <<<<< [ 22 - 1 = 21 ] [ 5/4 - 2/4 = 3/4 ]
= 21 3/4 (Answer)

23 1/4 - 1 1/2 =
Convert the mixed fractions to improper fractions
23 1/4 becomes 93/4 ( 4 x 23 + 1 and retain the denominator which is 4)
1 1/2 becomes 3/2 ( 2 x 1 + 1 and retain the denominator which is 2)
93/4 - 3/2 Find the least common denominator (LCD) or the smallest number (or multiples of 2 and 4) which is 4
93/4 - 6/4 -------------------> 6/4 ( LCD divided by 2 x 3)
87/4 Covert to mixed number by division
21 3/4 ====> the answer
