If you would like to know what is 3 X minus 1/4 equals 6/7, you can calculate this using the following steps:
3 * X - 1/4 = 6/7
3 * X = 6/7 + 1/4
3 * X = 24/28 + 7/28
3 * X = 31/28 /3
X = 31/28 / 3
X = 31/28 * 1/3
X = 31/84
The correct result would be 31/84.
We need to find out which 2 numbers round to the nearest tenth is 53.6.
