Four Go Age 7 to 11 Challenge Level This challenge is a game for two players. Before precision instruments were widely available, scientists and engineers had to get creative with ways to measure either very small or very large things. To multiply fractions, multiply the numerators and place them over the product of the denominators. The diagonal is essentially a hypotenuse of a 45-45-90 triangle, so d = 202. While both the absolute and relative comparisons are useful here, they still make it hard to answer the original question, since is it worth it implies there is some tradeoff for the gas savings. If you have unnecessary information, ignore it. The gas costs for the hybrid are about [latex]\displaystyle\frac{\$450.10}{\$1612.45}[/latex] = 0.279 = 27.9% lower than the costs for the standard Sonata.
