Question

please answer me please​

Answer 1

Answer:

Solution :-

1) $\dfrac{1}{10} + \dfrac{3}{6}$

$\implies\dfrac{3 + 15}{30}$

$\implies\dfrac{ \: \: \: \: \: \cancel{18}^{\: 3}}{\cancel{30}^{\: 5}}$

$\implies\dfrac{3}{5}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\:\dfrac{3}{5}$

2) $\dfrac{1}{10} - \dfrac{3}{6}$

$\implies\dfrac{3 - 15}{30}$

$\implies\dfrac{ \: \: \: \: \: \cancel{- 12}^{\: - 2}}{\cancel{30}^{\: 5}}$

$\implies\dfrac{- 2}{5}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\:\dfrac{- 2}{5}$

3) $\dfrac{7}{15} + \dfrac{1}{3} + \dfrac{2}{5}$

$\implies\dfrac{7 + 5 + 6}{15}$

$\implies\dfrac{ \: \: \: \: \:\cancel{18}^{\: 6}}{\cancel{15}^{\: 5}}$

$\implies\dfrac{6}{5}$

$\implies 1.2$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 1.2$

4) $\dfrac{7}{15} - \dfrac{1}{3} - \dfrac{2}{5}$

$\implies\dfrac{7 - 5 - 6}{15}$

$\implies\dfrac{2 - 6}{15}$

$\implies\dfrac{ - 4}{15}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{- 4}{15}$

5) $2\dfrac{3}{8} + 1\dfrac{1}{4}$

$\implies\dfrac{19}{8} + \dfrac{5}{4}$

$\implies\dfrac{19 + 10}{8}$

$\implies\dfrac{29}{8}$

$\implies 3.625$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 3.625$

6) $2\dfrac{3}{8} - 1\dfrac{1}{4}$

$\implies\dfrac{19}{8} - \dfrac{5}{4}$

$\implies\dfrac{19 - 10}{8}$

$\implies\dfrac{9}{8}$

$\implies 1.125$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 1.125$
