It would be 12 and 1/2 because 40% is 2 and 1/2 of 100 and then you do 5 times 2 and 1/2 and you get 12 and 1/2.

40% can be expressed as 40/100 or 0.4

[tex]\frac{40}{100} \times x = 5\\\\0.4 \times x = 5[/tex]

Divide both sides by 0.4 to isolate 'x'

[tex]0.4x = 5\\\\\frac{0.4x}{0.4} = \frac{5}{0.4}\\\\x = \frac{5}{0.4} \\\\\boxed{\bf{x = 12.5}}[/tex]

40% of 12.5 is 5.
