if a a line is 2 and 7/8ths long and u take 1/2 inch off? what will it be?
1/2 = 4/8
2 7/8 - 4/8 = 2 3/8
7/8 - 1/2 2 3/8
To determine the length of the line after taking off 1/2 inch, you will need to subtract 1/2 inch from the original length of the line, which is 2 and 7/8 inches.
To calculate, first convert the mixed fraction 2 and 7/8 to an improper fraction:
2 and 7/8 = (2 x 8 + 7)/8 = 23/8
Now, subtract 1/2 inch from 23/8:
23/8 - 1/2 = (23/8) - (4/8) = 19/8
The resulting fraction 19/8 represents the new length of the line after taking off 1/2 inch. To convert it back to a mixed number, divide the numerator (19) by the denominator (8):
19 ÷ 8 = 2 remainder 3
Therefore, the line will be 2 and 3/8 inches long after taking off 1/2 inch.
