To complete this question, all we have to do is divide the 8 cups of berries the chef has by the 2/3 cup of berries the chef will use to make each dessert. The equation we will use is as follows:
8 / = 12.
If the statement is true, the chef will be able to make 12 desserts.
10 x 25 = 250, well 20 x 25 is just double that, its 10 doubled x 25 so he probably just added it up. repeated addition really helps with times tables.
