How do you simplify the sum of #3/5 + 2/7#?

Answer 1

#31/35#

You can not directly add or subtract the top numbers of fractions unless the bottom numbers are all the same.

Both 5 and 7 will divide into 35 because #5xx7=35# '....................................................
Multiply #3/5# by 1 but in the form of #color(green)(1=7/7)# giving
#" "3/5color(green)(xx7/7) = 21/35# '..........................................................
Multiply #2/7# by 1 but in the form of #color(brown)(1=5/5)# giving
#" " 2/7color(brown)(xx5/5)= 10/35# '.......................................................... #color(blue)("Putting it all together"#
#" "3/5+2/7 " is the same as "21/35+10/35#

The correct way to write this is:

#" "3/5+2/7" " -=" "21/35+10/35#
#" "=31/35#

Answer 2

To simplify the sum of 3/5 + 2/7, you need to find a common denominator and then add the fractions together.

The common denominator for 5 and 7 is 35.

So, rewrite the fractions with the common denominator:

3/5 = (3 * 7) / (5 * 7) = 21/35 2/7 = (2 * 5) / (7 * 5) = 10/35

Now, add the fractions:

21/35 + 10/35 = 31/35

So, the simplified sum of 3/5 + 2/7 is 31/35.

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.
