jika p:q=9:17 dan p+q=546 maka nilai q-p=

Diketahui = p:q = 9:17
p+q = 546

Ditanyakan = q - p
Dijawab =
[tex]p = \frac{9}{9 + 17} \times 546 \\ = \frac{9}{26} \times 546 \\ = 9 \times 21 \\ = 189[/tex]
[tex]q = \frac{17}{9 + 17} \times 546 \\ = \frac{17}{26} \times 546 \\ = 17 \times 21 \\ = 357[/tex]
[tex]q - p = 357 - 189 \\ = 168[/tex]
Semoga membantu :-)
