To subtract fractions, you need to have a common denominator. In this case, the common denominator for 40 and 30 is 120.
First, let's convert both fractions to have the denominator of 120:
For 23/40:
Since 120 is divisible by 40, we can multiply both the numerator and denominator by 3 to get:
23/40 = (23 * 3) / (40 * 3) = 69/120
For 11/30:
Since 120 is divisible by 30, we can multiply both the numerator and denominator by 4 to get:
11/30 = (11 * 4) / (30 * 4) = 44/120
Now that we have both fractions with the same denominator, we can subtract them:
69/120 - 44/120 = (69 - 44) / 120 = 25/120
However, we should simplify the fraction if possible. Both the numerator and denominator have a common factor of 5, so we can divide by 5:
25/120 = (25/5) / (120/5) = 5/24
Therefore, the answer to the subtraction of 23/40 minus 11/30 is 5/24.
