How do you add #2\frac { 3} { 10} + 9\frac { 4} { 5}#?

Answer 1

#121/10# or #12 1/10#

First, we multiply the whole number by the denominator, add it to the numerator, and stack it on top of the same denominator to turn both mixed fractions into improper fractions.

#2 3/10+9 4/5#

#=>2 3/10=23/10# and #9 4/5=49/5#

Thus, we currently have:

#23/10+49/5#

The numerator and denominator of the second fraction are multiplied by the same number in order to preserve the fraction value and obtain the necessary denominator since the two denominators must be equal in order for them to be added.

#=>49/5xx2/2=98/10#

Presently, we possess:

#23/10+98/10=(23+98)/10=121/10=12 1/10#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
