Karim uses a photocopier to enlarge the triangle PQR diagram by 150%.

a) Write the ratio of the length of P' Q' to the length of PQ.

b) Is the ratio of the length P 'R' to the length PR equal to the ratio of the length P 'Q' to the length PQ?

c) Use your knowledge of ratios and percentages to explain the meaning of 'enlarging the PQR diagram by 150%'.

Result

r =  1.5
b=

Yes

No

r =

Step-by-step explanation:

$$\begin{gathered} r=|P^{\prime }{Q}^{\prime }|/|PQ| \\ r=150\%=\frac{150}{100}=\frac{3}{2}=1.5 \end{gathered}$$

$b=1$
