Four lemons cost P95.00. The following are ways to express it EXCEPT:
- A.4 is to 95
- B.4:95
- C.4 x 95
- D.4 for 95
Show answer & explanation
Answer: C. 4 x 95
The correct answer is C because 4 × 95 means multiplication (4 times 95 equals 380), which does not express the relationship "4 lemons cost P95.00." Options A, B, and D all correctly express a ratio or proportion: "4 is to 95" (A), "4:95" (B), and "4 for 95" (D) all mean 4 lemons for every 95 pesos.

- A.9:11
- B.8:9
- C.2:5
- D.13:15
Show answer & explanation
Answer: A. 9:11
To simplify a ratio, divide both numbers by their greatest common divisor (GCD). The GCD of 162 and 198 is 18. Dividing both numbers by 18 gives 162÷18 = 9 and 198÷18 = 11, resulting in the simplified ratio of 9:11.

The Lombardo siblings will be inheriting their late father's wealth in the ratio 4:3:3:2. The amount to be divided is P420,000.00. How will the division of the wealth be expressed?
- A.P140,000: P105,000: P105,000: P70,000
- B.P123,000: P105,000: P105,000: P87,000
- C.P134,000: P108,000: P108,000: P70,000
- D.P155,000: P115,000: P115,000: P35,000
Show answer & explanation
Answer: A. P140,000: P105,000: P105,000: P70,000
The ratio 4:3:3:2 totals 12 parts. Divide P420,000 by 12 to get P35,000 per part, then multiply each ratio component: 4×P35,000=P140,000, 3×P35,000=P105,000, 3×P35,000=P105,000, and 2×P35,000=P70,000.

Which of the following ratio could be simplified to 14:3?
- A.81:27
- B.120:85
- C.210:45
- D.180:60

A factory conveyer belt moves at a rate of 50 meters per 4 minutes. How far does it travel in an hour?
- A.750 m
- B.800 m
- C.900 m
- D.650 m
Show answer & explanation
Answer: A. 750 m
The conveyor belt travels 50 meters in 4 minutes. To find the distance in 60 minutes (1 hour), multiply the rate by how many 4-minute intervals fit in an hour: (60 ÷ 4) × 50 = 15 × 50 = 750 meters.

Based on item #9, how will you express the movement of the conveyer belt as a ratio in its simplest form?
- A.50:4
- B.12:10
- C.25:2
- D.5:4
Show answer & explanation
Answer: C. 25:2
To express a ratio in simplest form, you must divide both numbers by their greatest common divisor (GCD). The ratio 25:2 cannot be reduced further since 25 and 2 share no common factors other than 1, making it the simplest form of the conveyor belt's movement ratio.
