Question

How do I get the answer to this problem

Answer 1

Answer:
`(19)/(20) - (10)/(20) - (2)/(20)`

`(7)/(20)`

Explanation:

Since the Least Common Denominator is 20 (or the biggest number on the bottom in your case), you can multiply 4 and 10 by their corresponding number to get 20.

4 * 5 = 20

10 * 2 = 20

Now multiply the top and bottom by 5 and 2

`(5)/(5) *(2)/(4)` =
`(10)/(20)</p><p>[tex](2)/(2) *(1)/(10)` =
`(2)/(20)</p><p>Now subtract everything.</p><p>[tex](19)/(20) - (10)/(20) - (2)/(20)`

Its equals
`(7)/(20)` .

Answer 2

You do it, or ask someone

Explanation:

Because. Just because. That's logic.

jk.... 19/20 - 10/20 - 2/20

19/20 - 12/20

7/20
