Yes, five sixths is bigger than four twelfths (simplified: one third).
The answer is one.
You change five sixths into ten twelfths and three quarters into nine twelfths. Then you subtract the nine twelfths from the ten twelfths, which equals one twelfth.
Yes. Two twelfths equal one sixth, so it follows.
5/6 - 1/4 = 10/12 -3/12 = 7/12
10/12 + 9/12 = 19/12 = 1 and 7/12
One sixth plus four sixths equals five sixths, or 5/6.
Expressed as a mixed number in its simplest form, 1/12 + 10/12 + 11/12 = 1 5/6 or one and five sixths. Expressed as a decimal, this is equal to 1.83 recurring (that is, 1.83333...)
