NCERT Solutions For Class 6 Maths Chapter 7 Fractions Exercise 7.9 - 2025-26

Exercise 7.9

1.  Can you find three different fractional units that add up to 1? It turns out there is only one solution to this problem (up to changing the order of the 3 fractions)! Can you find it? Try to find it before reading further.

Solution: Yes, one solution to the problem of finding three different fractional units that add up to 1 is:

$\dfrac{1}{2} + \dfrac{1}{3} + \dfrac{1}{6} = 1$

This combination works because:

• $\dfrac{1}{2} = \dfrac{3}{6}$​

• $\dfrac{1}{3} = \dfrac{2}{6}$

• $\dfrac{1}{6}$ remains the same.

When you add them together:

$\dfrac{3}{6} + \dfrac{2}{6} + \dfrac{1}{6} = \dfrac{6}{6}$ = 1

So, $\dfrac{1}{2}$, $\dfrac{1}{3}$​, and $\dfrac{1}{6}$​ are the three different fractions that add up to 1.

2.  Can you find four different fractional units that add up to 1? It turns out that this problem has six solutions! Can you find at least one of them? Can you find them all? You can try using similar reasoning as in the cases of two and three fractional units—or find your own method! 

Solution: Here are four different fractional units that add up to 1, along with a few combinations:

One Solution:

1. $\dfrac{1}{2} + \dfrac{1}{3} + \dfrac{1}{6} + \dfrac{1}{6} = 1$

Six Solutions:

1. $\dfrac{1}{2} + \dfrac{1}{3} + \dfrac{1}{6} + \dfrac{1}{6} = 1$

2. $\dfrac{1}{2} + \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{1}{4} = 1$

3. $\dfrac{1}{4} + \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{1}{4} = 1$

4. $\dfrac{1}{2} + \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{1}{4} = 1$

5. $\dfrac{1}{3} + \dfrac{1}{3} + \dfrac{1}{3} + \dfrac{1}{3} = 1$

6. $\dfrac{1}{5} + \dfrac{1}{5} + \dfrac{1}{5} + \dfrac{1}{5} = 1$

Different Combinations of Four Different Fractions:

1. $\dfrac{1}{2} + \dfrac{1}{3} + \dfrac{1}{12} + \dfrac{1}{4} = 1$

2. $\dfrac{1}{4} + \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{1}{4} = 1$

3. $\dfrac{1}{5} + \dfrac{1}{10} + \dfrac{1}{10} + \dfrac{1}{10} = 1$
