Preparation for Algebra all Question Solutions :
Problem Set 54 :
Question no – (1)
Solution :
We know,
= 7 + 6 = 13
= 8 + 5 = 13
= 9 + 4 = 13
Three pairs of numbers whose sum is 13 are,
= (7 + 6) , (8 + 5) , (9 + 4)
Using this three equalities are,
= (7 + 6) = (8 + 5)
= (7 + 6) = (9 + 4)
= (8 + 5) = (9 + 4)
Question no – (2)
Solution :
We know,
= 10 + 8 = 18
= 25 –7 = 18
= 9 × 2 = 18
= 36/2 = 18
Four pairs of numbers, one for each of addition, subtraction, multiplication and division that make the number 18 are,
= (10 + 8) , (25 – 7) , (9 × 2 ) , (36 / 2 )
Equalities for each of them,
= (10 + 8) = (25 – 7)
= (9 × 2 )
= (36/2)
Problem Set 55 :
Question no – (1)
Solution :
(1) (23 + 4) = (4 + 23)
We know,
23 + 4 = 27
And 4 + 23 = 27
So, they are equal
(23 + 4) = (4 + 23) It is right
(2) (9 + 4) > 12
We know,
9 + 4 = 13
13 > 12
(9 + 4) > 12 It is right
(3) (9 + 4) < 12
We know,
9 + 4 = 13
13<12
(9 + 4) 138
We know,
138 = 138
138 > 138 It is wrong
(5) 138 < 138
We know,
138 = 138
138 5
We know,
25/5 = 5
So, 25/5 > 5 It is wrong
(9) (5 × 8) = (8 × 5)
We know,
5×8 = 40
8×5 = 40
40 = 40
(5 × 8) = (8 × 5) It is right
(10) (16 + 0) = 0
We know,
16 + 0 = 16
So,
(16 + 0) = 0 It is wrong
(11) (16 + 0) = 16
We know,
16 + 0 = 16
16 = 16
Thus, (16 + 0) = 0 It is right
(12) (9 + 4) = 12
We know,
9 + 4 = 13
So, (9 + 4) = 12 It is wrong
Question no – (2)
Solution :
(1) (45 ÷ 9) ___ (9-4)
We know,
49 ÷ 9 = 5
9 – 4 = 5
5 = 5
Hence, (45 ÷ 9 = (9-4)
(2) (6 + 1) ___ (3 × 2)
We know,
6 + 1 = 7
3 × 2 = 6
7 is greater than 6
(6 + 1) > (3 × 2)
(3) (12 × 2) ____ (25 + 10)
We know,
12 × 2 = 24
25 + 10 = 35
24 is less than 35
(12 × 2) < (25 + 10)
Question no – (3)
Solution :
(1) (1 × 7) = ( ___× 1)
We know,
1 × 7 = 7
7 × 1 = 7
7 = 7
So, the answer is – (1×7) = (7×1)
(2) (5 × 4) > (7 ×___)
We know,
5 × 4 = 20
7 × 2 = 14
20 is greater than 14
Therefore, the answer is – (5 × 4) > (7 × 2)
(3) (48 ÷ 3) < ( ___× 5)
We know,
48 ÷ 3 = 16
5 × 4 = 20
16 is less than 20
So, the answer is – (48 ÷ 3) (5 ×___ )
(4) (0 + 1) > (5 × ___)
We know,
0 + 1 = 1
5 × 0 = 0
20 is greater than 14
So, the answer is – (0 + 1) > (5 × 0)
(5) (35 ÷ 7) = (___ +___ )
We know,
35 ÷ 7 = 5
3 + 2 = 5
5 = 5
So, The answer is (35 ÷ 7) = (3 + 2)
(6) (6 – ___) < (2 + 3)
We know,
6 – 3 = 3
2 + 3 = 5
3 is less than 5
So, the answer is – (6-3) < (2+3)
Problem Set 56 :
Question no – (1)
Solution :
(1) The sum of any number and zero is the number itself.
Let any number be A
A + 0 = A
(2) The product of any two numbers and the product obtained after changing the order of those numbers is the same.
Let one number be A and another number be B
A × B = AB
change the order
B × A = BA
AB = BA
A × B = B × A
(3) The product of any number and zero is zero.
Let any number be A
A × 0 = 0
Question no – (2)
Solution :
(1) m – 0 = m
Let m be any number
Subtracting zero from any number gives the number itself
(2) n ÷ 1 = n
Let n be any number
Dividing any number by one gives the number itself.
