NCERT Solutions for Class 4th Maths Chapter 5 Sharing and Measuring
Updated on 2026-09-19
About this chapter
A part is a fraction of the whole only when all the parts are equal in size. Two equal parts give halves (1/2). Four equal parts give quarters (1/4). Three equal parts give thirds (1/3). The more people share one thing, the smaller each share becomes: 1/2 is bigger than 1/3, and 1/3 is bigger than 1/4. All the equal parts put back together make one whole: 5 pieces of 1/5 make 1 whole dhokla. Equal pieces can be joined: two 1/4 pieces make 1/2, and two 1/8 pieces make 1/4. We can also take a fraction of a group of things: 1/4 of 8 diyas is 2 diyas.

| Idea | What it means | How we write it | Where it comes in the chapter |
|---|---|---|---|
| Whole | The full thing, before we cut it | 1 | One full dhokla |
| Half | 1 of 2 equal parts | 1/2 | The dhokla shared by 2 people |
| One-third | 1 of 3 equal parts | 1/3 | The dhokla shared by 3 people |
| Quarter | 1 of 4 equal parts | 1/4 | The dhokla shared by 4 people |
| One-fifth | 1 of 5 equal parts | 1/5 | Mogra in 1 of the 5 garden strips |
| Two-fifths | 2 of 5 equal parts | 2/5 | Rose in 2 of the 5 garden strips |
| Equal parts rule | All the parts must be the same size | — | Bablu’s squares, page 78 |
| More parts, smaller share | Cutting into more equal parts makes each part smaller | 1/9 is smaller than 1/5 | Sumedha’s dhokla, pages 66–69 |
| Joining equal pieces | Equal pieces put together make a bigger piece | 2 pieces of 1/4 = 1/2 | Fraction chart, page 77 |
| Fraction of a group | Share the things into equal groups and take some groups | 1/4 of 8 = 2 | Meena’s 8 diyas, page 73 |
