Answer :
'what number' indicates an unknown value we can represent with 'x'
'is' indicates an equal sign.
25% = 0.25
'of' indicates multiplication.
x = 0.25 * 180
x = 45
'is' indicates an equal sign.
25% = 0.25
'of' indicates multiplication.
x = 0.25 * 180
x = 45
[tex]p\%=\frac{p}{100}\\\\25\%=\frac{25}{100}=\frac{25:25}{100:25}=\frac{1}{4}\\\\25\%\ of\ 180=\frac{1}{4}\ of\ 180=\frac{1}{4}\cdot180=\frac{180}{4}=\boxed{45}[/tex]
