Answer 1

To subtract mixed numbers, first convert them to improper fractions.

2 and three-fifths becomes 2 + 3/5, which is (2*5 + 3)/5 = 13/5.

1 and one-fourth becomes 1 + 1/4, which is (1*4 + 1)/4 = 5/4.

Now subtract the two fractions:

13/5 - 5/4

To subtract fractions, the denominators should be the same. Since the denominators are 5 and 4, we need to find a common denominator, which is 20.

13/5 becomes (13*4)/20 = 52/20.

5/4 becomes (5*5)/20 = 25/20.

Now subtract the fractions:

52/20 - 25/20 = (52 - 25)/20 = 27/20.

So, 2 and three-fifths minus 1 and one-fourth equals 27/20.

Answer 3

To subtract mixed numbers, first convert them to improper fractions.

2 and three-fifths becomes 2 + 3/5, which is equal to (2 * 5 + 3) / 5 = 13/5.

1 and one-fourth becomes 1 + 1/4, which is equal to (1 * 4 + 1) / 4 = 5/4.

Now subtract the two fractions:

13/5 - 5/4

To subtract fractions, you need to have a common denominator. Since 5 and 4 are not multiples of each other, we can find a common denominator by multiplying them: 5 * 4 = 20.

Now we need to convert the fractions to have a denominator of 20:

13/5 = (13 * 4) / (5 * 4) = 52/20

5/4 = (5 * 5) / (4 * 5) = 25/20

Now we can subtract the fractions:

52/20 - 25/20 = (52 - 25) / 20 = 27/20

So, 2 and three-fifths minus 1 and one-fourth equals 27/20.
