The sum of 2 1/5 + 1 3/5 is 3 4/5.
To find the sum of 2 1/5 + 1 3/5, you can follow these steps:
1. Convert the mixed fractions into improper fractions:
2 1/5 = (2 * 5 + 1) / 5 = 11/5
1 3/5 = (1 * 5 + 3) / 5 = 8/5
2. Add the two improper fractions together:
11/5 + 8/5 = (11 + 8) / 5 = 19/5
3. Simplify the fraction (if possible):
19/5 is an improper fraction, so we can convert it back to a mixed fraction:
19 divided by 5 is 3 with a remainder of 4.
Therefore, the sum of 2 1/5 + 1 3/5 is 3 4/5.
To add these fractions, we need to find a common denominator first. The denominators in this case are 5 and 5, so we don't need to do anything in this step.
Now, let's add the whole numbers: 2 + 1 = 3.
Next, we add the fractions: 1/5 + 3/5 = 4/5.
Finally, we combine the whole numbers and the fractions: 3 + 4/5 = 3 4/5.
Therefore, the sum of 2 1/5 + 1 3/5 is 3 4/5.
