How many times does 21 and two thirds go into 325?
You need to divide 3425 by 21 and 2/3 This is done by following the rule. "If you wish to divide by a fraction, turn it over and multiply instead". But we have to change the 21 and 2/3 into an "improper" fraction; that's the name for a "top heavy" fraction. So. changing 21 and 2/3 into thirds we have (21 x 3) + 2 = 65 thirds = 65/3 To divide by that, multiply by 3 over 65 instead So multiplying 325 x 65/3 we get 21125/3 = 7041 & 2/3
