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)

[tex]\frac{1}{3} + \frac{2}{5}[/tex]

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...

[tex]\frac{1 * 5}{3 * 5} = \frac{5}{15}[/tex]

[tex]\frac{2 * 3}{5 * 3} = \frac{6}{15}[/tex]

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

[tex]\frac{5}{15} + \frac{6}{15} =\frac{11}{15} \\\\\frac{11}{15}[/tex]

[tex]\frac{11}{15}[/tex]  is ur answer.

Hope this helped!

Answer:

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

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

Step-by-step 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
