85*60/100 = 51
85 - (40%) = 51

51 questions is 85% of 60 questions. Divide 51 by 60, then multiply by 100 to get the percentage (%). 51/60 = 0.85 x 100 = 85% (you may notice that 51/60 = 17/20, and multiplying by 5/5 gives you the same answer)
60 - 20% = 48 or 48/1
51 is 60% of 85
51 is what percent of 85:= 51 / 85= 0.6Converting decimal to a percentage:0.6 * 100 = 60%
85*60/100 = 51
85 - (40%) = 51
60 - (30%) = 42

First you do... 51 = ? 60 100 Then you cross-multiply the 51 and the 100 and get 5,100. Next you take the 5,100 and divide it by the 60 which gives you your final answer of 85%. ( I personally like to think of it as if your solving a right triangle trying to make a rectangle; in this problem it would be the 100, the 51, and the 60 and then the missing number would be the last corner to finish the rectangle. )
51 divided by 10 = 10%, which is 5.1. So 6 x 5.1 = 60%, which is 30.6
Answer: 453 The number given can be seen as a sequence of 63 60 56 51. Taking these as separate numbers: 60 is 63 minus 3 56 is 60 minus 4 51 is 56 minus 5 the numbers decrease by the (difference between the last two numbers plus 1) So, 51 minus 6 gives 45 and 45 minus 7 gives 38 The next three numbers are, therefore, 453
51 questions is 85% of 60 questions. Divide 51 by 60, then multiply by 100 to get the percentage (%). 51/60 = 0.85 x 100 = 85% (you may notice that 51/60 = 17/20, and multiplying by 5/5 gives you the same answer)
60*20/100=1260-12=48
60 - 20% = 48 or 48/1
