Answer:

[tex]14.4[/tex]$

Step-by-step explanation:

[tex] \frac{x}{40} = \frac{60}{100} [/tex]

[tex](60)40 = (x)100[/tex]

[tex]2400 = (x)100[/tex]

[tex] \frac{2400}{100} = \frac{(x)100}{100} [/tex]

[tex] \frac{2400}{100} = x[/tex]

[tex]24 = x[/tex]

[tex]x = 24[/tex]

[tex]40 - 24 = 16[/tex]

[tex] \frac{x}{40} = \frac{4}{100} [/tex]

[tex](4)40 = (x)100[/tex]

[tex]160 = (x)100[/tex]

[tex] \frac{160}{100} = \frac{(x)100}{100} [/tex]

[tex] \frac{160}{100} = x[/tex]

[tex]1.6 = x[/tex]

[tex]x = 1.6[/tex]

[tex]16 - 1.6 = 14.4[/tex]

[tex]14.4[/tex]$
