When you subtract 16 2/3 from 7 7/8 you will get 211/24 as a mixed number.
7 is an odd number. If you subtract an odd number minus an even number, you will always get an odd number. There is no way to avoid this.
== == 7/12 - 11/12 = -4/12 or -1/3.

Double the last digit, subtract it from the rest. If the result is divisible by 7, the whole number is divisible by 7.
The number is 72 because (72/9)-7 = 1
The end result is: -2 + s
Subtracting a positive number from any other number results in a lower value. For example, subtract 5 from 7: 7 - 5 = 2 It is exactly the same if the positive number is subtracted from a negative number. Subtract 5 from -3 for example: -3 - 5 = -8 The value of the result is lower and the result will always be negative.
5 x 6 x 7 = 210. 210 is the answer. proof 210 - 5 = 205/5 = 41 210 - 6 = 204/6 = 34 210 - 7 = 203/7 = 29
an example is 11 + -18 first you subtract 11 from 18 and get -7 now since you know that 7 is your answer this is how you got it keep 11 and change the additon sign(+) to a subtraction sign(-) then change negative eighteen (-18) to positive eightteen(18) know subtract 11-18 and you get -7
11

78/11 gives 7 with a remainder of 1, so the result is: 7 1/11
to subtract fractions you must first convert the fractions so that they have the same denominators, then subtract the numerators from each other.example1/11-1/7=common denominator = 771/11 * 7/7 - 1/7 * 11/11(Note: 7/7 and 11/11 are both equal to one so the value of each fraction does not change)7/77 - 11/77(7-11)/774/77Improved Answer:1/11-1/7 = -4/77 because 7/77-11/77 = -4/77
