Class 4 Maths Video Chapter 7 Money: Conversion, Addition & Subtraction

0:0:0: hello
0:0:1: students in today's video we will learn
0:0:4: about money we all know Indian currency
0:0:7: is rupees and PES so we will learn how
0:0:10: to read and write rupees and PES how to
0:0:13: convert Rupees to pesi and how to
0:0:15: convert PES to rupees and addition and
0:0:18: subtraction of money so let's
0:0:23: start first let's see how to read and
0:0:26: write figures in rupees and PES amount
0:0:29: of money can be written in two ways in
0:0:31: words as well as in
0:0:33: figures for example in words we can
0:0:36: write it as 3 rupees and 50 PES in
0:0:40: figures it is written as rupes
0:0:43: 3.50 children dot separates the rupees
0:0:46: from
0:0:47: pesi the left side has rupees and the
0:0:50: right side has
0:0:52: py the next example is 3 rupees and 5
0:0:56: PES in figures it is written as rupe pce
0:1:1: 3.05 make note that if PES is less than
0:1:4: 10 then write a zero after dot like if
0:1:8: there is 6 PES then in figures it will
0:1:11: be written as
0:1:14: 0.06 now let's see how to convert rupees
0:1:17: into pesi one rupee will be equal to 100
0:1:21: PES so to convert rupees into PES
0:1:24: multiply rupees by 100 and to convert
0:1:28: PES into rupees divide PES by 100 let's
0:1:33: solve few questions to understand
0:1:36: convert 8 rupees into PES to convert
0:1:39: rupees into PES multiply the amount
0:1:42: given in rupees by 100 and write P at
0:1:45: the end for PES so your rupees 8 equals
0:1:49: to 8 into 100 PES which is equal to 800
0:1:53: PES now let's see how to convert PES
0:1:56: into Rupees convert 850 50 PES into
0:2:1: Rupees to convert PES into Rupees divide
0:2:4: by 100 or count two digits from right
0:2:7: and put a dot there like here put a dot
0:2:11: before 50 and write Rupees at the
0:2:14: beginning for
0:2:15: rupees so 850 PES equals to rupees
0:2:21: 8.50 let's try some questions for
0:2:24: addition and subtraction of money first
0:2:27: question the price of some items in shop
0:2:30: are given below Harry wants to buy a
0:2:33: packet of milk pack of bread and a
0:2:35: bottle of jam how much does he have to
0:2:38: pay the
0:2:40: shopkeeper we have packet of milk of 23
0:2:43: rupees pack of bread at 12.7 rupees and
0:2:46: jar of Jam at 36.5
0:2:49: rupees so we have to add all of these to
0:2:53: get the total money let us arrange these
0:2:56: prices in
0:2:57: columns always remember to to write
0:3:0: rupees under rupees column and PES under
0:3:2: PES column you will observe that the dot
0:3:6: always come in a line now add the PES
0:3:9: first and then the
0:3:11: rupees adding PES 0 + 7 + 5 we get 12 so
0:3:17: we put two in the answer and one in the
0:3:20: carry now before adding rupees put a
0:3:23: point in the answer adding rupees 1 from
0:3:27: carry + 3 + 2 plus plus 6 we get 12 two
0:3:32: in the answer and one again in carry one
0:3:36: from carry plus 2 + 1 + 3 we get 7 so
0:3:42: the answer comes out to be 72.2
0:3:46: rup now if Harry gives 80 Rupees to the
0:3:49: shopkeeper how many does he have to
0:3:52: return for this let's subtract 72.2 from
0:3:57: 80 again write them in column and
0:4:0: remember to write rupees in rupes column
0:4:3: and PES in PES column first subtract PES
0:4:7: from PES and then rupees from
0:4:10: rupees we need to subtract two from zero
0:4:13: but zero is weaker than two so it
0:4:16: borrows from eight because rest of its
0:4:18: neighbors are also zero so zero borrows
0:4:23: from8 and becomes 10 and it reduces to
0:4:26: 7even now the next zero takes borrow
0:4:30: from 10 and becomes 10 and reduces 10 to
0:4:33: 9 now subtract 2 from 10 we get 8 next
0:4:39: before we subtract rupees from rupees
0:4:41: put a point in the answer then we
0:4:44: subtract two from 9 to get seven and
0:4:47: lastly 7 from seven to get zero the
0:4:51: answer comes out to be 7.8
0:4:54: rupees we hope that you have understood
0:4:57: the concept of money now here's a secret
0:5:0: on how you can study effectively with
0:5:3: the urv app you can learn with chapter
0:5:6: notes watch video lectures and solve McQ
0:5:9: tests of this chapter on
0:5:11: eduv and that's not all you also get
0:5:14: amazing courses for class 4 and much
0:5:17: more for your class 4
0:5:19: preparation thank you
