Fantom [35]

Step-by-step explanation:

Since we have given that

Number of hour Marco practiced the piano on Monday is given by

$\frac{7}{10}$

Number of hours Marco practiced the piano on Tuesday is given by

$1\frac{1}{4}=\frac{5}{4}\ hours$

1) For Adding :

Total number of hours he practiced on both Monday and Tuesday will be

$\frac{7}{10}+\frac{5}{4}\\\\=\frac{14+25}{20}\\\\=\frac{39}{20}\ hours$

2) For Subtraction,

Number of hour he practiced more on Tuesday than on Monday will be

$\frac{5}{4}-\frac{7}{10}\\\\=\frac{25-14}{20}\\\\=\frac{9}{20}\ hours$
