Question #bf43b

Answer 1

`6 2/3`

Explanation:

Let's start by making these into improper fractions:

`4 1/6 = 25/6`

`-2 1/2 = -5/2`

After that we can properly subtract them, as such:

`25/6 - (-5/2)`
`25/6 + 5/2`
`25/6+15/6` (Make the denominators the same number)
`40/6 = 6 2/3`

Hope this helps!

Answer 2

`6 2/3`

Explanation:

When you subtract change the sign of the number to be subtracted and add.
Before doing it change the numbers to full fraction
So we have
`4 1/6 = 25/6`
`2 1/2 = 5/2`
Now add them
`25/6 + 5/2 = 25/6 + 15/6 = 40/6`
Now simplify the fraction
`40/6 = 20/3 = 6 2/3`

Answer 3

`6 2/3`

Explanation:

If you look at a graphical number line, you can see that the negative of a negative number is just the "positive" (it just switches the direction along the line).

`4 1/6 - -2 1/2 = 4 1/6 + 2 1/2`
From here we just need to express both fractions with equal denominators. 2 is a factor of 6, so we will use 6.
`4 1/6 + 2 1/2 = 4 1/6 + 2 3/6 = 6 4/6` or `6 2/3`
