Question

Add the following fraction of 5/9+15/18​

Answer 1

Answer:

25/18

Step-by-step explanation:

5/9 can be converted to 10/18

now we have same denominator

thus 10/18 + 15/18 = 25/18

this could be also written as - 1  7/18

Answer 2

Answer:

The answer is 25/18 ,in decimal form is 1.39

Step-by-step explanation:

First note the following rule in addition of fraction :

Step 1: Make sure the bottom numbers (the denominators) are the same

Step 2: Add the top numbers (the numerators), put that answer over the denominator

Step 3: Simplify the fraction (if needed)

In this question the bottom numbers are different

We need to make them the same before we can continue, because we can't add them like that.

The number "18" is twice as big as "9", so to make the bottom numbers the same we can multiply the top and bottom of the first fraction by 2, like this:

UPPER NUMBER× 2

$\frac{5}{9}$    

LOWER NUMBER × 2

Then it become $\frac{10}{18}$

       Important: you multiply both top and bottom by the same amount,

                 to keep the value of the fraction the same

Now the fractions have the same bottom number ("18"), and our question looks like this:

$\frac{10}{18}$ + $\frac{15}{18}$

The bottom numbers are now the same, so we can go to step 2.

Step 2: Add the top numbers and put them over the same denominator:

$\frac{10}{18}$ + $\frac{15}{18}$ = $\frac{25}{18}$

Now the answer is 25/18 because it does not need to be simplified

A Rhyme To Help You Remember

♫ "If adding or subtracting is your aim,

The bottom numbers must be the same!

♫ "Change the bottom using multiply or divide,

But the same to the top must be applied,

♫ "And don't forget to simplify,

Before its time to say good bye"
