A cookie recipe calls for 3 1/6 cups of sugar for every 2 4/6 cups of flour if you need if you made a batch of cookies using 8 cups of flour how many cups of sugar would you need?

9 1/2. If I am right could I get brain?

Answer:You´d need 9 1/2 of sugarStep-by-step explanation:To solve this you just need to do a simple rule of three, where you know that you need to use 3 1/6 cups of sugar for every 2 4/6 of flour, so how many cups will you need to cook 8 cups of flour?, so you arrange the data the next way:[tex]\frac{3\frac{1}{6} }{2\frac{4}{6} }=  \frac{x}{8} \\x=\frac{8(3\frac{1}{6}) }{2\frac{4}{6} }\\x=\frac{\frac{152}{6} }{\frac{16}{6} } \\x=\frac{152*6}{6*16} \\x=\frac{152}{16} \\x=9 \frac{8}{16} \\x=9\frac{1}{2}[/tex]So you get that you will need 9 1/2 cups of sugar for the 8 cups of flour keeping the ratio of 3 1/6 of sugar for every 2 4/6 of flour.
