1 minus 11/21 = 10/21
11 and 3/4 gallons of gas
5/6 − 1/12 = 3/4
The way to figure this out is to convert the whole number into a fraction with the same denominator as the fraction being subtracted. Let's do this one. 1 - (5/12) = (12/12) - (5/12) = At this point, you have 12 over 12 minus 5 over 12, and to work a fraction like that where you have a common denominator, you can take the numerators and subtract them and put the result over 12. It will look like this: (12 - 5) / 12 = 7/12 That 7/12 is your answer. You don't even have to reduce it.
9/10 minus 1/10 is 4/5
11/12 minus 7/12 is 1/3
It is: 12-5/12-1/12 = 11 and 1/2 or 11.5
11/12 − 1/2 = 5/12
1 and 9/12 minus 5/6 = 11/12
11/12 − 1/6 = 54/72 which reduces to 3/4
11/12 = 0.91666666666666671/3 = 0.33333333333333330.9166666666666667 - 0.3333333333333333 = 0.5833333333333333
73/4
1 and 5/6 minus 1/4 = 11/6 - 1/4 = 22/12 - 3/12 = 19/12 = 1 ans 7/12
one minus eleven twelfths = 1 - 11/12 = 12/12 - 11/12 = 1/12
12 - 1 = 11
11/12
5/12 minus 1/9 = 11/36 in its simplest form
