If\(\frac{p}{q}\) =\(\frac{r}{s}\)=\(\frac{t}{u}\)=\(\frac{2}{5}\), then what is the value of(4p+3r+7t):(4q+3s+7u)?
Answer & explanation
Correct answer: option 3
\(\frac{p}{q}\) =\(\frac{r}{s}\)=\(\frac{t}{u}\)=\(\frac{2}{5}\)
Find (4p+3r+7t):(4q+3s+7u)
(4 × 2 + 3 × 2 + 7 × 2 ) : (4 × 5 + 3 × 5 + 7 × 5 )
28 : 70
2 : 5
