Question

find the sum of the following fractions.
2/12+5/8=
​

Answer 1

Answer:

$\frac{19}{24}$

Step-by-step explanation:

$\frac{2}{12} + \frac{5}{8}$

LCM OF 12 AND 8: 24

$\frac{4 + 15}{24} = \frac{19}{24}$

Answer 2

Answer= 19/24

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 2 by 8, and get 16, then we multiply 12 by 8 and get 96.

Now for the second term. You multiply 5 by 12, and get 60, then multiply 12 by 8 and get 96.

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

16

96

+

60

96

Step 2

Since our denominators match, we can add the numerators.

16 + 60 = 76

Answer:

76/96

Step 3

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

76

96

÷ 2 =

38

48

Let's try dividing by that again...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

38

48

÷ 2 =

19

24

Let's try dividing by that again...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

Nope! So now we try the next greatest prime number, 17...

Nope! So now we try the next greatest prime number, 19

Nope! So now we try the next greatest prime number, 23...

No good. 23 is larger than 19. So we're done reducing.

There you have it! Here's the final answer to 2/12 + 5/8
