Question

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the way. Which decimal number shows the portion of the distance Sandy skips?

Answer 1

0.2

Explanation:

Convert the walking to percent

`(1)/(2) * 100 = 50`

Add both skateboarding and walking

`30\% + 50\%\\\\= 30 + 50\\\\= 80`

Now, subtract that from a whole percent

`100 - 80 = 20\\\\20\%`

Convert it to a decimal

`20\% = (20)/(100) \\\\=20 / 100\\\\= 0.2`

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
