Answer 1

Answer:

mate your question is not written properly i mean in improper way plzz check it

Step-by-step explanation:

first day deposit = 5000 rupees

second day withdraw = 3200 rupees

remaining rupees = 5000 - 3200

= 1800 rupees

again deposit = 2700 rupees

now, total rupees = 1800 + 2700 = 4500

so, her balance on third day = 4500 rupees

Answer 2

Step-by-step explanation:

Each lesson - 1 1/2 hours

Changing mixed fraction into improper fraction

1 1/2 = 3/2.

4 1/2 = 9/2

1 lesson - 3/2 hours

9/2 hours - ? lessons

$\dfrac{9}{2} \div \dfrac{3}{2}$

$\dfrac{9}{2} \times \dfrac{2}{3} = 3$

Hence :

In 9/2 hours , Teacher can teach 3 lessons at night.
