What is 2 1/5 + 4 1/10?a. 6 3/10 b. 6 3/5 c. 6 1/10 d. 6 1/5

2 1/5+4 1/10
=11/5+41/10
=(11/5)*2+41/10
=22/10+41/10
=63/10
6 3/10
answer A.6 3/10

2 1/5 + 4 1/10

First change the mixed fractions into improper fractions. This is done by multiplying the denominator (5) by the whole number (2) and the adding that to the numerator (1), keeping the denominator the same. Do this to the other fraction too.
11/5 + 41/10

The next step is to make them have the same denominator. The only one you need to change is 11/5 to get the denominator to be 10, multiply it by 2.
22/10 + 41/10
63/10

Now figure out how many times 10 can go into 63. It can go in 6 times, so that will be your whole number. Now think how much you have left over (63-60), which is 3.
So your mixed fraction will look like this:
6 3/10

A. 6 3/10
