What is the difference of 3 - 2 and 2/3?

dolphi86 [110]

3-2= Here you are taking away 2 from 3
2/3= Here you are taking that two and breaking it down into 3 smaller groups of numbers----Example: If you have 2 apples and you are serving 3 people, you will cut the apple into slices and distribute the slices evenly into 3 little ziploc bags.

Hope this helps.

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify.

Point (2, 2)

Point (7, 7)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(7 - 2)^2 + (7 - 2)^2}$
[Order of Operations] Evaluate: $\displaystyle d = 5\sqrt{2}$
