Subtract: 12 3/8 - 8 1/5

Answer 1

To subtract 8 1/5 from 12 3/8, we first need to find a common denominator. The least common denominator between 8 and 5 is 40.

12 3/8 = 12 * 8/8 + 3/8 = 96/8 + 3/8 = 99/8
8 1/5 = 8 * 5/5 + 1/5 = 40/5 + 1/5 = 41/5

Now that we have both fractions with the same denominator, we can subtract them:

99/8 - 41/5

To subtract these fractions, we need to find a common denominator, which is 40:

(99 * 5)/(8 * 5) - (41 * 8)/(5 * 8)
495/40 - 328/40
167/40

Therefore, 12 3/8 - 8 1/5 = 167/40 or 4 7/40.
