## Adding Fractions With Like Denominators

We'll be separating the following examples in two parts.

## First case of Adding Fractions with Like Denominators

Even by saying what we see on the left hand side: two thirds – we got the answer. :-)

This one has little simplifying at the end. Two fourths = one half.

Now let’s finally look at fifths and sixths.

Same story here, adding numerators…

Again a little reducing of fractions from sixths to thirds.

## Second case of Adding Fractions with Like Denominators

These were the fifths, now let’s finish with sixths.

## How to solve Math Word Problems With Fractions

00:00 welcome to math with mr. J in this video

00:05 we're going to take a look at adding

00:07 fractions word problems and we're going

00:11 to go through two problems or situations

00:13 where we'll use adding in order to get

00:17 us to our answer so let's jump right in

00:19 the number one here where we have Jose

00:22 spent two-fifths of his money on new

00:25 shirts and one-half of his money on new

00:29 shoes what fraction of his money has

00:32 been spent and what fraction is still

00:35 left so let's take the information from

00:39 the problem here we have two-fifths on

00:42 shirts and we're combining that with how

00:45 much he spent on shoes which would be

00:48 adding together whenever we have

00:49 combining of things it's going to be

00:53 addition so two-fifths plus one-half now

00:59 we do not have a common denominator so

01:03 we need to find one four five and ten so

01:06 the common denominator is going to be

01:09 ten four five minute - so I'm going to

01:11 rewrite the problem to the right here

01:14 and we have a common denominator of 10

01:19 well two-fifths I know five times two

01:22 gives me that denominator of 10 so I

01:25 need to do that to the top in order to

01:28 get an equivalent fraction and 2 times 2

01:31 is 4 so 2/5 is 4/10 equivalent to 4

01:37 tenths now we need to rename 1/2 well 2

01:43 let's do that to the top to get our

01:46 equivalent fraction 1 times 5 is 5 now

01:52 we're ready to add because we have a

01:54 common denominator 4 plus 5 is 9 and we

02:00 keep our denominator of 10 the same so

02:03 this is how much he spent he has spent

02:07 tenths of his money so 9/10 has been

02:11 spent so now we need to figure out what

02:15 fraction of his money is left how do we

02:18 get to the full one whole or ten out of

02:21 ten so what's left so if you spent nine

02:24 tenths that means one tenth is left

02:28 that's what will get us to the full hole

02:31 of ten out of ten or a hundred percent

02:34 of his money so nine tenths has been

02:37 spent and again one tenth is left let's

02:43 take a look at number two

02:45 Quinn red two-fifths of her book over

02:48 the weekend and one sixth on Monday what

02:53 fraction of the book has she read what

02:56 fraction is left so again we're

02:59 combining two-fifths from the weekend

03:02 and then one sixth from Monday so that's

03:06 going to be two-fifths plus 1/6 we do

03:14 not have a common denominator so we need

03:16 to rename with a common denominator in

03:19 order to add five and six the common

03:23 denominator is going to be 30 so let's

03:28 rename I know 5 times 6 is 30 so let's

03:32 do it to the top 2 times 6 is 12 6 times

03:39 5 will give me my denominator of 30 so I

03:43 need to do 1 times 5 is 5 so here we

03:50 have 12 plus 5 is 17 keep our

03:54 denominator of 30 so she read a total of

04:00 17 thirtieths this is how much she has

04:04 read so we need to figure out what

04:08 fraction is left how do we get to 30 out

04:11 of 30 or 100% of the book what's

04:14 remaining well 13 thirtieths would get

04:19 over 30 or the a hundred percent of the

04:22 book so we have thirteen thirtieths left

04:28 and think about it seventeen plus that

04:32 thirteen gets us to again the 30 out of

04:36 30 which is one whole or 100 percent of

04:39 the book so there you have it there's a

04:42 couple of situations or word problems

04:44 where we had to add fractions in order

04:47 to find the solution thanks so much for

04:51 watching until next time peace

Analysis: To solve this problem, we will subtract two fractions with unlike denominators. Analysis: To solve this problem, we will add two mixed numbers, with the fractional parts having like denominators

A good place to start before you run into some serious different denominator fraction problems. If we're having 2 or more fractions with like denominators – adding them is easy – we add their numerators and that's it. No heavy science there
