Question: 5/12 − 2/5= 1/60​


A. The answer 1/60 is not reasonable because ​5/12​ is closer to 1 than to ​1/2​, and ​2/5​ is closer to 0 than to ​1/2​, making the difference close to 1/2. ​

B. The answer​ 1/60 ​is not reasonable because ​5/12​ is closer to ​1/2​ than to 1, and ​2/5​ is closer to 0 than to ​1/2, making the difference close to​ ​1/2​. ​

C. The answer 1/60 is reasonable because both fractions are closer to 1/2 than they are to 0, making the difference close to 0.

D. The answer 1/60 is reasonable because both fractions are closer to 1 than they are to 1/2, making the difference close to 0.

Answer:

C

Step-by-step explanation:

It is reasonable: the answer is both reasonable and correct because 5/12 - 2/5 = 1/60. This is because using cross multiply, 5 x 5/12 = 25/60, 12 x 2/5 = 24/60. 25/60 - 24/60 = 1/60.

Both are closer to half: half out of 12 would be 6/12 and 0 would be 0/12, so 5/12 is closer to half because 5/12 is closer to 6/12 than 0/12. Half out of 5 would be 2.5/5 and 0 would be 0/5, so 2/5 is closer to half because 2/5 is closer to 2.5/5 than 0/5.

The difference is close to 0: 1/60 is very close to 0. It's only worth 0.016.

The answer is b bc if you know how to work it out then you can find it
