Question: What is [[p]] percent of [[a]]?
Percentage solution with steps:
Step 1: Our output value is [[a]].
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,119=100%.
Step 4: Similarly, x=15%.
Step 5: This results in a pair of simple equations:
[[a]]=100%.....................(1).
x=15%.........................(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
[[a]]/x=100%/[[p]]%
Step 7: Again, the reciprocal of both sides gives
x/[[a]]=[[p]]/100
Thus x=
Therefore, [[p]]% of [[a]] is
