## 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:

6480 |

80 |

## Step 2

Since our denominators match, we can include the numerators.

64 + 60 = 124

So the prize is:

12480 |

## 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:

12480 |

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 |

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 + 6/88 |

10 |

8 |

20 |
