Question

73 is 20% of what number?

Answer 1

20% = 73/x * 100% 

20%/100% = 73/x 

0.20 = 73/x 

x = 73/0.20 

x = 365

Answer 2

Make an equation.

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

So we have:

$\sf73=0.20\cdot~x$

Multiply:

$\sf73=0.20x$

Divide 0.20 to both sides:

$\sf~x=\boxed{\sf365}$
