Question

you estimate that a jar contains 68 marbles is 60. find the error round your answer to the nearest tenth

Answer 1

Answer: 13.3%

Step-by-step explanation: So the problem is to find out how much is 68 percent if 60 is 100%, we can use a rule of three, simple, direct proportion to do it:

60 -------> 100%

68 --------> x

x = (68)(100)/60

x = 113.3

therefore 68 is 113.3% of 60, which means that the error is of:

113.3 - 100 = 13.3%
