Question

If p +  3r is equal to 150 percent of 6r, what is the value of p/r ?

p + 3r = 9r

lgbasallote · Answer

p + 3r is 150% of 6r so...

$$ p + 3r = \frac{150}{100} \times 6r$$
so... $$100(p + 3r) = 150 \times 6r$$
$$\implies 100p + 300r = 900r$$
$$\implies 100p = 900 r - 300r$$
$$\implies 100p = 600r$$
divide both sides by 600r
$$\implies \frac{100p}{600r} = 1$$
simplify
$$\implies \frac {p}{6r} = 1$$
cross multiply..
$$\implies \frac pr = 6$$
does that help?
