Step 1

We can"t add two fractions with different denominators (the bottom number). Therefore you require to acquire a typical denominator - both bottom numbers have to match. To do this, you"ll main point the platform times every other... Yet the numerators need to change, too. They acquire multiplied through the other term"s denominator.

You are watching: What is 7/8 plus 7/8

So us multiply 7 by 10, and get 70, then us multiply 8 by 10 and also get 80.

*

Do the very same for the second term. Us multiply 3 through 8, and get 24, climate multiply 8 by 10 and get 80.

*

So currently our fountain look choose this:

70
80
+24
80

Step 2

Since our denominators match, us can include the numerators.

70 + 24 = 94

Now we have an answer.

94
80

Step 3

Last of all, we should simplify the fraction, if possible. Have the right to it be diminished to a less complicated fraction?

To discover out, we shot dividing that by 2...

Are both the numerator and also the denominator same divisible by 2? Yes! therefore we minimize it:

94
80
÷ 2 =47
40

Now, try the same number again.

Nope. Shot the following prime number, 3...

Nope. Try the following prime number, 5...

Nope. Shot the following prime number, 7...

Nope. Try the following prime number, 11...

Nope. Try the next prime number, 13...

Nope. Shot the next prime number, 17...

Nope. Try the following prime number, 19...

Nope. Shot the following prime number, 23...

Nope. Try the next prime number, 29...

Nope. Try the following prime number, 31...

Nope. Shot the next prime number, 37...

Nope. Try the next prime number, 41...

No good. 41 is bigger than 40. For this reason we"re done reducing.

Congratulations! Here"s your final answer to 7/8 + 3/10
