difference between 1 - ½ = ½ the estimate
and 10/12-3/8=4/3 the actual
The first equation, 1 - ½ = ½, represents the difference between one whole unit and a half unit. So, subtracting half from one leaves a remaining half, which is the estimate.
The second equation, 10/12 - 3/8 = 4/3, represents the difference between two fractions. When subtracting fractions, we need to make sure they have the same denominator. In this case, we need to find a common denominator for 12 and 8, which is 24.
10/12 can be rewritten as 20/24, and 3/8 can be rewritten as 9/24. Subtracting 9/24 from 20/24 gives us 11/24.
Therefore, the actual difference between 10/12 and 3/8 is 11/24.
