Adam had 91dollars. if he spent 21 dollars on new books, what is the ratio of the money he still has to money he's spent.

3/13

Step-by-step explanation:

ratio is another way to say fraction, so we have 21/91.  This can be reduced if we divide by 7: 21/7 = 3, 91/7 = 13.  Now we have 3/13.  You can write it as 3:13 or 3/13.

828. all there is to it!

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!
