Michael is baking cookies. His cookie recipe calls for 1 4/3 cups sugar and makes 24 cookies. If he wants to scale the recipe to make exactly 18 cookies, how many cups of sugar will he need? Express your answer as a mixed number.
+237 => for 24 cookies he need = 1 4/3 cups of sugar
i.e 7/3 cups
1 cookie he need = 7/3 / 24
= 7/3 * 1/24
for 18 cookies he need = 7/(3 * 24 4) * 18 * 3
= 7/4 cups
i.e 1 3/4 cups
