Starla is making hot cocoa. She plans to multiply the recipe by 4 to make enough hot cocoa for the whole class. If the recipe calls for \(\large \frac{1}{2}\) teaspoon vanilla extract, will she need more than \(\large \frac{1}{2}\) teaspoon or less than \(\large \frac{1}{2}\) teaspoon of vanilla extract to make all the hot cocoa?
Miles is planning to spend \(\large \frac{2}{3}\) as many hours bicycling this week as he did last week. Is Miles going to spend more hours or fewer hours bicycling this week than last week?
