Given: The numbers are  $\frac{5}{7}$& $\frac{9}{7}$ To do: Find 3 irrational number between the given numbers. Solution: The numerators in this question are 5 and 7. You can see denominators are same. We know 5 = $\sqrt{25}$ and 9 = $\sqrt{81}$. So, all square roots between $\sqrt{25}$ and $\sqrt{81}$ which are not perfect squares are ... Read More

To do: Write two irrational number between $\frac{3}{7}$&$ \frac{1}{11}$ Solution:To solve this question, first we need to find LCM of the denominators and convert them into like fractions. LCM of denominators 7 and 11 is 77. To convert into like fractions We will multiply numerator and denominator of $\frac{3}{7}$ ... Read More

On the basis of the physical state of fuel, they are classified into three: solid, liquid, gaseous state.Example: Solid:- Wood, cow dung cakes and agricultural waste.  Liquid:- Kerosene, diesel and petrol. Gas:- CNG, Natural Gas, Helium.

Given: $ \frac{2}{9} \times\left(\frac{-3}{4}\right) $ To do: Solve the expression Solution: $ \frac{2}{9} \times\left(\frac{-3}{4}\right) $ Open the brackets $\frac{2}{9}\times\frac{-3}{4}$ $\frac{2\times-3}{9\times4}$ $\frac{-6}{36}$ $-\frac{1}{6}$ Therefore the value of the expression is $\frac{-1}{6}$

Size of Camphor tablet decreased due to sublimation process. Camphor tablet possess the property of converting solid to gaseous form without converting to liquid. Thus its due to this sublimation property, the camphor tablet sublimes.Similar property was observed in daily life with napthalene balls kept along with woollens. Napthalene balls ... Read More
