Question: Use the conversion graph to the right to answer the following questions.

a) Convert 7 pounds into Indian Rupees

b) Convert 775 Indian rupees into pounds 

 

a) We want to find 7 on the x-axis, draw a vertical line up to the graph, and then draw a horizontal line across from the point where we meet the graph. Where that horizontal line hits the y-axis will be our value in rupees. So, this looks like

Therefore, we get that £7 is equivalent to 600 Rupees.

b) We want to find 775 on the y-axis, draw a horizontal line across to the graph, and then draw a vertical line down from the point where we meet the graph. Where that vertical line hits the x-axis will be our value in pounds. So, this looks like

Therefore, we get that 775 Rupees is equivalent to £9.
