Answer 1

Just so you know, this is in Words and Wordplay, not math.

You have to convert them so they all have the same denomonator.

1. 19/20-(1/2-3/10)

                1/2=5/10

                 5/10=10/20

    19/20-(10/20-3/10)

                 3/10=6/20

    19/20-(10/20-6/20) Do the equation inside the parenthesis

    19/20-4/20

     15/20, which simplified equals 3/4.

2. 1/10+1/100+1/1000

    Convert all denomonators to 1000.

    100/1000+10/100+1/1000

    111/1000

Don't worry, you'll get better with practice! (And a calculator lol)

Answer 2

If you can master fractions you are way ahead of a lot of students.

19/20 - (1/2 - 3/10)  

Convert the fractions to the least common denominator.  In this case, twentieths.

It becomes then  19/20 - (10/20 - 6/20)

or   1/20*(19 - 10 + 6)  =  3/20

I would remind the other two responsers that when you subtract a negative number you ADD it.

The second one would be  100/1000 + 10/1000 + 1/1000 = 111/1000 or

in decimal form .111

Answer 3

the first one is 3/4

the second one is 111/1000
