Step-by-step explanation:

On monday marco practiced the piano for 7/10 hour. On Tuesday he practiced for 1 1/4 hours each day write a question that involves adding or subtracting fractions

A follow up question to this will be ,

How many hours did Marco practice in the first two days?

on monday=7/10

Tuesday=1 1/4

7/10+5/4

lcm=20

(14+25)/20=39/20 hours

2. What is the difference between his hours of practice on Tuesday and Monday

We have to subtract his hours of practice on monday from Tuesday, since tuesday is greater

5/4-7/10

(25-14)/20

11/20

Answer 2

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

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