A student compared - 1/4 and -0.3. He changed -1/4 to the decimal -0.25 and wrote, “Since 0.3 is greater than 0.25, -0.3 is greater than -0.25”. What was the student’s error?

Solution:

Given

A student compared -1/4 and -0.3

By changing -1/4 to decimal as -0.25

We know that

0.3 is greater than 0.25

Here -0.3 is less than -0.25

Error = -0.3 > -0.25

Therefore, the student’s error is -0.3 > -0.25.

✦ Try This: A student compared - 1/2 and -0.55. He changed -1/2 to the decimal -0.5 and wrote, “Since 0.55 is greater than 0.5, -0.55 is greater than -0.5”. What was the student’s error?
