Answer: 2 and 7/12
Step-by-step explanation: To subtract 4 - 1 and 5/12, first subtract the fractions. Since 4 has no fraction, imagine the fraction 0/12.
Notice however that we can't subtract 0/12 - 5/12.
So, let's rewrite 4 and 0/12 as 3 + 1 and 0/12 or 3 + 12/12 by changing 1 and 0/12 into an improper fraction.
Now we have 3 and 12/12 - 1 and 5/12.
Now we can subtract our fractions 12/12 - 5/12 and we get 7/12. Next we subtract our whole numbers 4 - 1 to get 3.
So 5 - 1 and 5/12 is 2 and 7/12.
