The number of hours Ashu studied on different days of a week are as follows.
Monday: 4 hours
Tuesday: `4(1)/(2)` hours
Wednesday : 5 hours
Thursday : `3(1)/(2)` hours
Friday : 4 hours
Saturday: 6 hours
Find the average number of hours in a day Ashu studied in that week.

Answer

To find the average number of hours Ashu studied in a week, we will follow these steps:

### Step 1: Write down the data
We have the following data for the number of hours Ashu studied each day:
- Monday: 4 hours
- Tuesday: 4.5 hours (which is `4(1)/(2)`)
- Wednesday: 5 hours
- Thursday: 3.5 hours (which is `3(1)/(2)`)
- Friday: 4 hours
- Saturday: 6 hours

### Step 2: Convert mixed numbers to decimal
We already have the data in decimal form:
- Monday: 4 hours
- Tuesday: 4.5 hours
- Wednesday: 5 hours
- Thursday: 3.5 hours
- Friday: 4 hours
- Saturday: 6 hours

### Step 3: Sum the total hours studied
Now we will add all the hours together:
\[ 4 + 4.5 + 5 + 3.5 + 4 + 6 \]

Calculating step by step:
- \(4 + 4.5 = 8.5\)
- \(8.5 + 5 = 13.5\)
- \(13.5 + 3.5 = 17\)
- \(17 + 4 = 21\)
- \(21 + 6 = 27\)

So, the total hours studied in the week is \(27\) hours.

### Step 4: Count the number of days
The number of days Ashu studied is \(6\) (from Monday to Saturday).

### Step 5: Calculate the average
To find the average, we divide the total hours by the number of days:
\[ \text{Average} = \frac{\text{Total Hours}}{\text{Number of Days}} = \frac{27}{6} \]

Calculating the division:
- \(27 \div 6 = 4.5\)

### Final Answer
The average number of hours Ashu studied in a day during that week is \(4.5\) hours.
