Question

3 plus 27 divided by (4 plus 5) Find the sum 1/3 plus 2/5

Answer 1

3 plus 27 divided by (4 plus 5) = 6

Find the sum 1/3 plus 2/5 = 11/15

Explanation:

Find the sum 1/3 plus 2/5

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 1 by 5, and get 5, then we multiply 3 by 5 and get 15.

1/3 times 5

Now for the second term. You multiply 2 by 3, and get 6, then multiply 3 by 5 and get 15.

2/5 times 3

We now have a new problem, that looks like this:

5

15

+

6

15

Step 2

Since our denominators match, we can add the numerators.

5 + 6 = 11

Answer:

11 /15

Step 3

Now, do we need to simplify this fraction?

1 /3 + 2 /5= 11 /15

Answer 2

4.) 6

5.)
`(11)/(15)`

Explanation:

4.

PEMDAS

Parenthesis, Exponents, Multiplication, Division, Adition, Subtraction.

3 + 27 ÷ ( 4 + 5 )

Do the parenthesis first ( 4 + 5 )

3 + 27 ÷ 9

Do the division next ( 27 ÷ 9)

3 + 3

Now addition.....( 3 + 3)

5.

`(1)/(3) + (2)/(5)`

In order to find the sum between these 2 fractions, we need to find a common denominator, and in this case, it can be 15...

`(1 * 5)/(3 * 5) = (5)/(15)`

`(2 * 3)/(5 * 3) = (6)/(15)`

Now that we have a common denominator, we can add them up...

`(5)/(15) + (6)/(15) =(11)/(15) \\\\(11)/(15)`

`(11)/(15)` is ur answer.

Hope this helped!
