The document discusses three types of proportions: 1. Direct proportion - when one quantity increases, the other increases at the same rate and vice versa. 2. Inverse proportion - when one quantity increases, the other decreases and vice versa. 3. Partitive proportion - a whole is divided into parts proportional to a given ratio. It then provides four example problems and asks to identify which type of proportion each illustrates and solve them.

1. THREE
TYPES OF
PROPORTION

2. 1. DIRECT PROPORTION-
When one quantity increases,
the other quantity increases at
the same rate and vice versa.
EX: The bus fare for an
80 km trip is P65. how
much is the bus fare for
a 320 km trip?

3. 2. INVERSE PROPORTION-
When one quantity increases,
the other quantity decreases,
and vice versa.
EX : If 6 men can plow
a field in 2 days. How
long will 3 men do it?

4. 3. PARTITIVE PROPORTION
A whole is divided into
parts that is proportional to
the given ratio.
EX : The sum of two
numbers is 215. If the
ratio is 2:3, find the larger
number.

5. IDENTIFY THE TYPE OF
PROPORTION THAT THE
FOLLOWING PROBLEMS
ILLUSTRATE. THEN SOLVE THE
PROBLEMS.
1. It takes 3 salesmen 8 days to
sell 5, 000 boxes of soap. If 2
more salesmen are added, how
long will it take them?

6. 2. If 3 eggs cost P8.00, how much
will 12 eggs cost?
3. Three boys sold garlands in the
ratio of 2:3:4. Together they sold
225 garlands. How many garlands
did each boy sell?
4. A basket of food is sufficient to
feed 15 persons for 3 days. How
many days would it last for 10
persons?
