13/15.
24 minus 1/6 is 23 5/6.
45/5 is 8 because 8x5=45. 8-2=6. So the answer is 6.
68
5/8 - 6/5 = 25/40 - 48/40 = -23/40 = -(23/40)
38/6 - 15/6 = 23/6 or 3 and 5/6
6/7 minus 1/5 is 23/35.
6/5 - (-2/9) 6/5 + 2/9= 64/45
23 - 6 = 17
32*5 - 6/2 = 9*5 - 6/2 = 45 - 3 = 42
4 + 4 * 6 - 5 = 4 + 24 - 5 = 28 - 5 = 23
4 5/6 divide 2 3/5 1st step ; convert to improper fractions. Hence 29/5 divide 13/5 2nd step ; Remember the rule for division of fractions. 'CHANGE THE SIGN TO MULTIPLY(X) AND INVERT (TURN OVER) THE RIGHT HAND FRACTION'. Then proceed as multiplying fractions. Hence 29/5 X 5/13 3rd step ; Cancel down any common factors; '5' in this case. Hence 29/1 X 1/13 4th step ; multiply 29/13 5th step ; Convert to a mixed fraction/number. Hence 2 3/13 the answer !!!!!
81 - 6 - 45 - 12 = 18
