Question

Find the ragio p:r if p:a=1:2, a:b=2:3, b:c=5:1, c:r=3:2​

Answer 1

Answer:

p : r = 5 : 2

Step-by-step explanation:

Expressing the ratios in fractional form, then

$\frac{p}{r}$ = $\frac{p}{a}$ × $\frac{a}{b}$ × $\frac{b}{c}$ × $\frac{c}{r}$

  = $\frac{1}{2}$ × $\frac{2}{3}$ × $\frac{5}{1}$ × $\frac{3}{2}$

   = $\frac{30}{12}$

  = $\frac{5}{2}$

Thus ratio p : r = 5 : 2
