First, convert both mixed fraction to improper fractions
3 and 1/8 = 25/8
2 and 3/8 = 19/8
Subtract numerators only (top numbers).
25 19 6
--- - --- = ---
8 8 8
If they're asking you for a fraction in simplest form:
6 3
--- = ---
8 4
2/4 - 1/8 = 4/8 - 1/8 = 3/8
5 8th of a cup is 1/2 a cup plus 2 tablespoon
5/6 - 1/8 / 1/2 = 5/6 - 1/4 = 10/12 = 3/12 = 7/12.
Four, because 4/8 = 1/2 There are obviously 8 1/8ths in a whole so half of that amount is obviously 4 1/8ths, which can be written as either 4/8ths or more correctly as 1/2.
2/8 is 1/4 which is a quarter which is 25%
The equivalent fraction of 2/8 is 1/4
It is: minus 1/2
1/2 of 3/8 = 3/16
2 3 8ths +5 7 8ths
There are two (2) 8ths in a quarter inch. This means that there are 8 8ths in a whole inch.
You asked about "to the minus" so we will talk about integers to the minus. Such as 2 to the minus 2. This means 1 over 2 to the positive two. In general a to the minus b is 1/a to the b
2/3 minus 1/6 is 1/2
