## Demonstration:

1) Money Word Problem With Addition

Seetha received Rs {15.25} for working on Friday night and  Rs.{17.75} for working on Saturday night. How much did she make in total?

Solution: Since we know that the word “ total “ conveys addition operation, let us add the amount of rupees mentioned.

i.e., (15.25 + 17.75)

Therefore Seetha made Rs.33  in total.

2) Money Word Problem With Subtraction.

Ramu has {Rs.25.00} to spend at the video game store. He buys a used game for {Rs15.83}. How much money does he have left over?

Solution : Since we know that the word “ left over “ conveys subtraction  operation, let us subtract the amount of rupees mentioned.

Therefore Ramu has Rs.9.17 left over.

3) Money Word Problem With Multiplication.

Surya wants to buy a chocolate bar for {Rs.0.75}. If he buys {4} bars, how much total money will he spend?

(Rs.0.75 x 4)

Count the number of decimal places in 0.75. There are 2 decimal places.

The 7 is in the tenths place and the 5 is in the hundredths place.

Multiply 75 x 4 = 300

Put the decimal point back into the product. 3.00

Surya will have to spend Rs. 3.00.

4) Money Word Problem With Division.

Kumar received {Rs24.75} for his birthday. He wants to split the money into groups to save for {three things}: show tickets, stationaries, and toys.  If he wants the same amount for each activity, how much money will he put into each group?

Solution :

(Rs.24.75 ÷ 3)

Divide whole Rs first (24 ÷ 3 = 8)

Divide Paisa next (0.75 ÷ 3 = 0.25)

Add Rs. and Paisa. Rs.8 + 0.25 = Rs.8.25

Write the answer. Kumar will put Rs.8.25 in each group.
