12/5ths = 2 and 2/5ths 2 and 2/5ths - 1 = 1 and 2/5th
2/3 minus 1/12 is 7/12.
it's 1/12
-6 TIMEs 2 and 2/5 = -12 and-12/5 or -14 and 2/5 or minus 14 and 2/5ths
2 minus one third is 1 and two thirds.
2 and 2 5ths... its really not that hard...
11/12 minus 2/3 is 1/4.
2/3 - 12 = -11 1/3 or minus eleven and one third.
2 and 1/12
2/3 = 4/6 = 8/12, 8/12 - 5/12 = 3/12
12/5
2 - 1/3 = 12/3 or 5/3
To answer this by hand, you would need to change the 2/3 to 8/12. 8/12-2/12=6/12 or 1/2.
2/3 = 8/12 - 5/12 = 3/12 or 1/4
or 5 and one third
12/15 - 10/15 = 2/15
67/ 12 or 5 7/12 http://www.freeonlinecalculator.net/calculators/math/mixednumbers.php
