1. Find the sum [Regroup and calculate]
(i) 4 hundreds + 16 tens = ?
(ii) 6 hundreds + 12 tens = ?
(iii) 7 hundreds + 17 tens = ?
(iv) 9 hundreds + 15 ones = ?
Solution:
(i) 4 hundreds + 16 tens
= 4x100 + 16x10
= 400 + 160
= 400 + (100 + 60)
= (400+100)+60
= 500 + 60
= 560 Ans.
(ii) 6 hundreds + 12 tens
= 6x100 + 12x10
= 600 + 120
= 600 + (100 + 20)
= (600+100)+20
= 700 + 20
= 720 Ans.
(iii) 7 hundreds + 17 tens
= 7x100 + 17x10
= 700 + 170
= 700 + (100+70)
= (700+100)+70
= 800 + 70
= 870 Ans.
(iv) 9 hundreds + 15 ones
= 9x100 + 15x1
= 900 + 15
= 915 Ans.
2. 9 hundreds = ?
(i) 900
(ii) 90 tens
(iii) 900 ones
Answer: (i), (ii) and (iii)
3. 12 + 32 = 32 + _____
Answer: 12
4. 88 + 0 = ____
Answer: 88
5. Write true and False.
(i) 14 + 44 = 44 + 14
(ii) 70 + 12 = 82
(iii) 19 tens = 9 tens + 1 ones
(iv) 1 tens + 1 tens = 10 ones
Answer:
(i) True [Know: Addends position change Rule]
(ii) True
(iii) False
19 tens = 19x10 = 190
(iv) False
1 tens + 1 tens = 2 tens = 20 ones
6. Fill in the blanks.
(i) 20 + 30 + 10 = ____
(ii) 20 + 24 = 24 + ____
Answer:
(i) 60
(ii) 20
7. Regroup and add the following with same format.
(i) 4 tens + 19 ones
(ii) 6 tens + 22 ones
(iii) 5 tens + 19 ones
(iv) 3 tens + 33 ones
Solution:
(i) 4 tens + 19 ones
= 4 tens + (10 ones + 9 ones)
= 4 tens + 1 tens + 9 ones
= 5 tens + 9 ones (Ans.)
(ii) 6 tens + 22 ones
= 6 tens + 20 ones + 2 ones
= 6 tens + 2 tens + 2 ones
= 8 tens + 2 ones (Ans.)
(iii) 5 tens + 19 ones
= 5 tens + 10 ones + 9 ones
= 5 tens + 1 tens + 9 ones
= 6 tens + 9 ones (Ans.)
(iv) 3 tens + 33 ones
= 3 tens + 30 ones + 3 ones
= 3 tens + 3 tens + 3 ones
=6 tens + 3 ones (Ans.)
8. Add
(i) 36 + 4
(ii) 43 + 5
(iii) 54 + 27
(iv) 73 +44
(v) 57 + 7
(vi) 82 + 44
(vii) 96 + 23
Answer:
(i) 40
(ii) 48
(iii) 81
(iv) 117
(iv) 64
(vi) 126
(vii) 119
9. In a resturent, there were 99 men, 32 women and 12 children. How many people were there in total?
Solution:
99 + 32 + 12
= 9 tens + 9 ones + 3 tens + 2 ones + 1 ten + 2 ones
=(9 tens + 3 tens + 1 ten) + (9 ones + 2 ones + 2 ones)
= 13 tens + 13 ones
= 13 tens + 1 tens + 3 ones
= 14 tens + 3 ones
= 140 + 3
= 143 (Ans)
