#4#

dividing by a fraction

Change the #div# to #xx# and flip the fraction which follows.

"Multiply by the reciprocal" is what this indicates.

This is evident in daily life when:

Finding "half of it" is equivalent to "dividing something by two."

#12 div 2 = 12 xx 1/2 = 1/2 xx 12 = 6#

Here, we have:

#1/2 div 1/8#

= #1/2 xx8/1#

= #1/cancel2 xxcancel8^4/1#

=#4#

[This actually means there are 4 portions of #1/8# each in #1/2#]
