Q1) 9/4 x (-7/5 x 1/2) = (9/4 x -7/5) x 1/2
Answer : 9/4 x -7/10 = -63/20 x 1/2
= -63/40 = -63/40 [By associativity]
Q2) Supermarket table lamp = 870 x 1/5
= 174 = 870 - 174 = 696
∴ The price offer by Supermarket is Rs. 696
Electric shop table lamp = 920 x 1/10
= 92 = 920 - 92 = 812
∴ The price offer by Electric shop is Rs. 812
Hence, We should buy table lamp from Supermarket.
Q3) Shyama bought total fruits is 5 kg 300 g and, 3 kg 250 g
The total fruits she bought is 5,300 + 3,250 = 8,550
Sarala bought total fruits is 4 kg 800 g and 4 kg 150 g
The total fruits she bought is 4,800 + 4,150 = 8,950
Hence, Sarala bought more fruits.
Q4) 7.5 - [2.25 ÷{1.25 - 0.5(1.5 - 0.75 - 0.5)}]
⇒ 7.5 - [2.25 ÷{1.25 - 0.125}]
⇒ 7.5 - [2.25 ÷ 1.125]
⇒ 7.5 - 2
⇒ 5.5
Q5) 2/5 + [8/3 x -12/4+{4/5-2/3}]
⇒ 2/5 + [8/3 x -12/4+ 1/3]
⇒ 2/5 + [-24/3+ 1/3]
⇒ 2/5 + -23/3
⇒ -46/15
