Answer

$\frac{6}{10}$ = 0.6 but $\frac{6+5}{10 + 5}$ = $\frac{11}{15}$ = 0.7

Work Step by Step

Let us take a fraction $\frac{6}{10}$ which is equal to 0.6 Now, consider a random whole number, say, '5' . On adding this number to both the numerator and denominator, the value of the above fraction changes to 0.7. $\frac{6+5}{10 + 5}$ = $\frac{11}{15}$ = 0.7
