A recipe calls for 1/3 cup of sugar for 1 batch. How many batches can be made with 2 cups of sugar.

Answer 1

2 divided by 1/3 = 2 times 3 = 6 batches for 2 cups of sugar

division by 1/3 is the same as multiplication by 3.

change division to multiplication by inverting the divisor. 1/3 inverted is 3/1 =3. Just flip the fraction upside down.
