Ratios of cross sectional areas of wires

2.3) Two wires have the same length and the same resistance but are made up of different materials. The resistivities of these materials are 2.69 Ω and 2.28 Ω. Obtain the ratio of the smaller cross-sectional area to the greater cross-sectional area.

You really don't have to do much with this is you don't want. If you understand that resistance, resistivity and area have a linear relationship and they want a ratio of less than one, then the answer is just 2.28/2.69.
