Answer 2

Step-by-step explanation:

Given: Harshana read 1/4 hours on Monday, 3/4 hours on Tuesday, 75 minutes on Wednesday, 3/2 hours on Thursday and 2 hours on Friday.

To find: How many hours does she read from Monday to Friday?

1️⃣ 5 hours and 40 minutes

2️⃣ 5 hours and 50 minutes

3️⃣ 6 hours and 30 minutes

4️⃣ 5 hours and 45 minutes

Solution:

Add total hours of reading,convert 75 minutes into hours by division of 60 as shown

$= \frac{1}{4} + \frac{3}{4} + \frac{75}{60} + \frac{3}{2} + 2\:hours$

$= \frac{1}{4} + \frac{3}{4} + \frac{5}{4} + \frac{3}{2} + 2$

take LCM

$= \frac{1 + 3 + 5 + 6 + 8}{4}$

$= \frac{23}{4}\:hours$

Now convert this into mixed fraction to

$\frac{23}{4} = 5 \frac{3}{4}\:hours$

Convert 3/4 hours into minutes

$\frac{3}{4} \: hours = \frac{3 \times 60}{4} \: minutes$

$\frac{3}{4} \: hours = 45 \: minutes$

Therefore,

Harshana reads 5 hours and 45 minutes.

Final answer:

Harshana reads 5 hours and 45 minutes.
