One minute is 60 seconds so 2 minutes are 120 seconds :)))
If 12 is 15% of a number than you could double 12 and get 24. The reason for this is because 15%*2 is 30% so than 12*2 would be 30% of a number. So 30% of a number is 24. If you than look at the 15% again you than will want to do 12*3 and get 46 as your answer.
X-2.13=5.3 x= 5.3 + 2.13 x = 7.43
+2.13
Process:
Start by isolating the variable by itself, in this case we add 2.13 to the -2.13 as whatever we do to one side of the equation we do to the other hence we add 2.13 to 5.3 which will become x = 7.43 and we can verify our answer by substituting our answer for x
7.43 - 2.13 = 5.3
Step one: Divide 10 by 100 to get 0.1 or 0.10 (they both mean the same thing)
Step two: Multiply 0.1 or 0.10 by 60 to get your answer which is 6.
