20% = 73/x * 100% 

20%/100% = 73/x 

0.20 = 73/x 

x = 73/0.20 

x = 365

Make an equation.

'is' is an equal sign
20% = 0.20
'of' is multiplication
'what number' is 'x'

So we have:

[tex]\sf73=0.20\cdot~x[/tex]

Multiply:

[tex]\sf73=0.20x[/tex]

Divide 0.20 to both sides:

[tex]\sf~x=\boxed{\sf365}[/tex]
