If you would like to know how many sixths are in 4, you can calculate this using the following steps:
n ... the number of sixths
n * 1/6 = 4
n = 4 * 6
n = 24
The correct result would be: 24 sixths are in 4.
To find this, multiply both the numerator and denominator by the same number. For example, 8 x 8 =64, and 10 x 8=80, so 64/80 would be an example of an equivalent ratio. Others could be 16/20 or 48/60. Hope this helps.
