Translate

• Panjang sebenarnya sebuah pesawat adalah 45 meter. Jika panjang model miniatur pesawat adalah 18 cm, berapakah skala miniatur pesawat tersebut?

Miniature scale

• Actual length (PS) = 45 m
• Models length (PM) = 18 cm
• Miniature scale (S) = ...

[tex] \sf S = ( \frac{PM}{PS} )[/tex]

[tex]\sf S = ( \frac{18 \: cm}{45 \: m}) [/tex]

[tex]\sf S = ( \frac{18 \: cm}{45 \times \red{100} \: cm} )[/tex]

[tex]\sf S = ( \frac{18 \: cm}{4.500 \: cm} )[/tex]

[tex]\sf S = ( \frac{18 \: : \: 18 }{4.500 \: : \: 18} )[/tex]

[tex]\sf S = ( \frac{1}{250} )[/tex]

[tex]\sf S = \red{1 : 250}[/tex]

So, Miniature scale is 1 : 250
