4/3 - 1/3 is 3/3 or 1.
1/3, or 0,333... or 33,33 %.
Yes
Because 1over3 seems right so that's y it's 1over3
4/12 = 1/3
4/8 minus 1/3 is 1/6
2/3 * 2 1/3 = 2/3 * 7/3 = 14/3
1/3 is .3333 repeating forever. To get this you divide 1 by 3.
2/3
2/3 + 4/6 = 4/3
basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.
0.5
Yes.
