1 and 1/2
The wording is ambiguous. If the questions means, "From what number can you subtract one-half to get a result of zero?" then the answer is one-half. (1/2) - (1/2) = 0 If the question means, "From what number can you subtract half of the number to get a result of zero?" then the answer is zero. 0 - (1/2)0 = 0
6 and 1/2
1
The answer is 1/4. There are 4 fourths in a whole. Convert 1/2 into 2/4, then subtract 1/4
= 1/2 - 1/3 = 1/6
1/2 is a half or 0.50 1/3 is a third or 0.33 a half minus a third = 0.17
3/8 minus 1/2 is -1/8
3/4 - 1/2 = 3/4 - 2/4 = 1/4
21/9 - 1/2 = 1.8333
minus one half
It is: 7/8-1/2 = 3/8
