NCERT Solutions for Class 5th Maths Chapter 2 Fractions

About this chapter
A fraction is a part of a whole. In 1/3, the bottom number 3 (the denominator ) tells how many equal parts the whole was cut into. The top number 1 (the numerator ) tells how many of those parts we took. Cut a chapati into 4 equal parts and take 3 — you have 3/4 of the chapati. The whole matters. Tamanna says 1/3 of one chocolate is bigger than 1/2 of the other, and she is right — her chocolates are different sizes. 1/2 of a 4-square bar is 2 squares; 1/3 of a 9-square bar is 3 squares. To compare two fractions fairly, both must come from the same whole. Then 1/2 is always more than 1/3. Equivalent fractions name the same part with different numbers. Cut a 1/2 piece into 2 equal bits and you get two 1/4 bits, so 1/2 = 2/4. Cut each part into more parts and both numbers grow together: 1/3 =

| Word | What it means | Where it appears | Example |
|---|---|---|---|
| Whole | The full thing before it is cut | Page 17, the two chocolates | One full paratha |
| Fraction | A number for a part of a whole | Chapter title, page 17 | 3/4 of a chapati |
| Denominator | The bottom number — how many equal parts the whole was cut into | Comparing Fractions — Same Denominator, page 22 | In 2/3, the denominator is 3 |
| Numerator | The top number — how many parts were taken | Comparing Fractions — Same Numerator, page 23 | In 2/3, the numerator is 2 |
| Equal parts | Parts of exactly the same size | Playing with a Grid, page 17 | A grid of 48 equal squares |
| Equivalent fractions | Different fractions that show the same part of the same whole | Page 18 and Making Equivalent Fractions, page 20 | 1/3 = 2/6 = 3/9 = 4/12 |
| Fraction kit | Cut-out pieces of 1/2, 1/3, 1/4, 1/6, 1/8, 1/12 … used to build a whole | Fun with Fraction Kit, page 18 | Two 1/4 pieces cover one 1/2 piece |
| Number line | A straight line where 0 to 1 is split into equal steps | Pages 24–28 | 1/4, 2/4, 3/4, 4/4 = 1 |
| Fraction greater than 1 | Top number bigger than the bottom number | Fractions Greater Than 1, page 24 | 9/4 = 2 1/4 |
| Mixed number | A whole number and a fraction written together | Pages 24 and 26 | 5/2 = 2 1/2 |
| Reference (benchmark) | A known fraction you compare others against | Pages 29 and 30 | Comparing with 1 and with 1/2 |
| Half | One of two equal parts, 1/2 | Comparing Fractions with Reference to 1/2, page 29 | 6/12 = 1/2 |
