This reviewer covers the DepEd Most Essential Learning Competencies (MELC) in Grade 5 Mathematics. Master each topic below to prepare for quizzes, periodical tests, and assessments.
Operations on Fractions
Multiply and divide fractions and mixed numbers; add and subtract dissimilar fractions fluently.
To divide by a fraction, multiply by its reciprocal (flip it). 6 ÷ ½ = 6 × 2 = 12.
Decimals
Add, subtract, multiply, and divide decimals; round decimals to a given place.
When adding or subtracting decimals, line up the decimal points. When multiplying, count the total decimal places in both factors.
Ratio, Proportion, and Percent
Express ratios, find equivalent ratios, and convert among fractions, decimals, and percents.
| Fraction | Decimal | Percent |
|---|---|---|
| 1/2 | 0.5 | 50% |
| 1/4 | 0.25 | 25% |
| 3/4 | 0.75 | 75% |
Percent means "per hundred". To turn a decimal into a percent, move the decimal point two places right: 0.45 → 45%.
Geometry and Volume
Find the area of triangles, parallelograms, and trapezoids; compute the volume of cubes and rectangular prisms.
