How do you add #5\frac { 9} { 10} + 2\frac { 5} { 8}#?

Answer 1

Convert both into improper fractions.

#5 9/10 = (5(10) + 9)/10 = 59/10#
#2 5/8 = (2(8) + 5)/8 = 21/8#

So the expression becomes

#59/10 + 21/8#

Multiply fractions by a common factor to get the same denominator:

#59/10 * 8/8 + 21/8 * 10/10#
#= 472/80 + 210/80#
Then just add them to get #682/80# and simplify:
Answer: #341/40 = 8 21/40#

Answer 2

To add ( 5\frac { 9} { 10} + 2\frac { 5} { 8} ), first convert both mixed numbers to improper fractions, then add them together:

( 5\frac {9} {10} = \frac {5 \times 10 + 9} {10} = \frac {59} {10} )

( 2\frac {5} {8} = \frac {2 \times 8 + 5} {8} = \frac {21} {8} )

Next, find a common denominator, which is 40 in this case.

( \frac {59} {10} = \frac {59 \times 4} {10 \times 4} = \frac {236} {40} )

( \frac {21} {8} = \frac {21 \times 5} {8 \times 5} = \frac {105} {40} )

Now add the fractions:

( \frac {236} {40} + \frac {105} {40} = \frac {236 + 105} {40} = \frac {341} {40} )

So, ( 5\frac {9} {10} + 2\frac {5} {8} = 6\frac {21} {40} )

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.
