Step 1

We can"t include two fractions with various denominators (the bottom number). For this reason you require to get a common denominator - both bottom numbers have to match. To carry out this, you"ll main point the platform times each other... However the numerators need to change, too. They obtain multiplied by the other term"s denominator.

You are watching: 8*10^6

So us multiply 8 by 8, and get 64, then us multiply 10 through 8 and also get 80.

*

Do the same for the 2nd term. Us multiply 6 by 10, and get 60, then multiply 10 through 8 and also get 80.

*

So currently our fountain look prefer this:

64
80
+60
80

Step 2

Since our denominators match, we can include the numerators.

64 + 60 = 124

So the prize is:

124
80

Step 3

Last the all, we must simplify the fraction, if possible. Can it be diminished to a less complicated fraction?

To uncover out, we shot dividing the by 2...

Are both the numerator and the denominator same divisible by 2? Yes! for this reason we alleviate it:

124
80
÷ 2 =62
40

So much so good... Let"s try to division by the number again.

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

62
40
÷ 2 =31
20

So far so good... Let"s shot to division by the number again.

No good. So following you try the following prime number, i m sorry is 3...

No good. So next you try the next prime number, i beg your pardon is 5...

No good. So following you shot the following prime number, i beg your pardon is 7...

No good. So following you shot the following prime number, i beg your pardon is 11...

No good. So following you shot the next prime number, i beg your pardon is 13...

No good. So next you try the next prime number, i m sorry is 17...

No good. So following you try the next prime number, i beg your pardon is 19...

No good. So next you try the next prime number, i m sorry is 23...

No good. 23 is larger than 20. For this reason we"re done reducing.

And we"re done! Here"s the last answer come 8/10 + 6/8
8
10
+6
8
=31
20
