6Numerical Reasoning Task
- The Marriage Problem
- In a certain town, 3/5 of the women are married
to 2/3 of the men. - What fraction of the adults in the town are
married? -
7The Marriage Problem
- Sample 1
- Since 3/5 of the women are married to 2/3 of the
men, 5/8 of the adults are married. - Sample 2
- 3/5 2/3
8The Marriage Problem
- Sample 3
- 3/5 of the women are married
- to 2/3 of the men are married
- so 19/30 of the adults are married.
9The Marriage Problem

10Numerical Reasoning Task 1½ ½
- There were 1½ pizzas left over. Juanita shared
the leftovers with her friend, Rachel. How much
pizza did they each get? - Yan has1½ ounces of gin and it takes ½ an ounce
of gin to make a cosmo. How many drinks can she
make? - It takes Kamal 1½ hours to clean his room. His
bother said they could each do ½ the work. How
long did it take them? - I have a total of 1½ square yards of fabric. The
fabric is ½ yard wide. How long is the fabric? - Bobby has 1½ feet of rope. Thats enough for ½ a
skipping rope. How much rope is needed for a
whole skipping rope?
