What is the width to length ratio of the rectangle below? (write in simplified form)

Find how many times the width is the length for the given rectangle.

John and Ramesh took up a job on contract. John worked $7$ days and Ramesh $6$ days. They got $₹6500$ as wages which they divided in the ratio of their investments. How much did each get in $₹$?

Draw a line $AB$ of length $9 \mathrm{centimetres}$. A point $P$ is to be marked on it, such that the lengths of $AP$ and $PB$ are in the ratio $1:2$. How far from $A$ should $P$ be marked? Compute this and mark the point.

Draw a line $15 \mathrm{centimetres}$ long. A point is to be marked on it, dividing the length in the ratio $2:3$. Compute the distances and mark the point.
