Suppose a cookie recipe calls for cups of flour. If you have cups of flour total, how many batches of cookies can you make?
(a)
Draw a picture representing the situation, and use pictures to solve the problem.
(b)
Identify whether the problem is asking “How many groups?” or “How many in one group?” or something else entirely.
(c)
You find another recipe that calls for cups per batch. If you have cups of flour, how many batches of these cookies can you make? Again use pictures to solve the problem.
(d)
Somebody once told you that “to divide fractions, you invert and multiply.” Discuss how this rule is manifested in this problem.
You have snazzy stainless steel containers (both the same size), which hold a total of cups of flour. How many cups of flour does container hold?
(a)
Draw a picture representing the situation, and use pictures to solve the problem.
(b)
Identify whether the problem is asking “How many groups?” or “How many in one group?” or something else entirely.
(c)
It turned out that the 6 cups of flour filled exactly of your containers. How many cups of flour does container hold? Again use pictures to solve the problem.
(d)
Somebody once told you that “to divide fractions, you invert and multiply.” Discuss how this rule is manifested in this problem.
