Ryan was adding numbers on a number line. he started at 56 and then he added 37. he wrote that his answer was 83. is ryan's answer reasonable? a. no, it is not reasonable because if you round the numbers 55 + 35 = 90, so the answer should be a bit greater than 90. b. yes, it is reasonable because when you add two numbers together, the answer will always be greater than either number. c. yes, it is reasonable because 50 + 30 = 80, so the answer must be greater than 80.
