Answer:
RATIO AND PROPORTION
(Finding the Missing Value)
Question:
Find the value of n in the equation 5:10 = n:30.
1. Transform the given ratio into fractional form.
[tex]\huge\sf{\frac{5}{10} = \frac{n}{30}}[/tex]
2. Multiply the means and extremes of the given, or simply just cross-multiply it.
[tex]\sf{5 (30) = 10 (n)}[/tex]
[tex]\sf{150 = 10n}[/tex]
3. Dividing both sides by 10 to get the value of n.
[tex]\sf{\frac{150}{10} = \frac{10n}{10}}[/tex]
[tex]\boxed{\purple{\sf{15 = n}}}[/tex]
