Order of operations are important here and you need to work from left to right:
x = 6 / 3 / 8 ; 6/3 is 2
x = 2/8
x = 1/4
x = 0.25
3 over 4 divided by 6 is 0.125 or 1/8.
6/8 = 3/4 8/6 = 4/3
3 over 4 Divide 6 and 8 by a common factor of 2 to get 3 and 4 6 divided by 2 / 8 divided by 2 = 3/4
it is 6 3/4 divided by 1/8 invert 1/8 and multiply 3/4 * 8/1 = 24/4 = 6
16
13/8 ÷ 3/4 = 11/6 or 15/6
13/8 ÷ 3/4 = 11/6 or 15/6
16
1 and 1/3 divided by 1/6 = 4/3 x 6/1 = 24/3 = 8
That's the same as 6 times 8/3 which simplifies to 16.
7/8 / 3/4= 7/8 x 4/3== 7/6
5/8 divided by 3/4 = 5/8 multiplied by 4/3 (5 x 4) / (8 x 3) = 20/24 = 5/6
