What is 3. 2/15 simplified
coldgirl [10]
Hi there!

Okay, so I was a bit confused by your question, but I tried to make it a bit easier and work out.

There was two ways I did this because I didn't want to NOT answer your question!

What about this:

3.2/15 cannot be simplified lower than what it is. Decimal form is 0.2133333 (repeating). I answered this part because I didn't know what 3. was (I at first thought it was part of the numerator. But now that I look at it again it may have been a question number. But just in case, I answered it like this anyway.)

Next!

I solved 2/15, which also cannot be simplified down lower than what it is. It's decimal form is 0.133333 (another repeating decimal.)

And so as you can see I answered two problems for you. If these are incorrect, let me know!

Hope this helps!
