Step-by-step explanation:
according to BODMAS rule,
(g). (7÷7×7+7-7)-(5-5+5×5÷5)
= ( 1×7+7-7) - ( 5-5+5×1)
= (14-7) - ( 5-10)= 7-(-5) = 7+5 = 12
(h). 10÷[3+{5-(12÷14)}]
= 10 ÷ [ 3+{5-6/7}]
= 10 ÷ [ 3 + 29/7]
= 10 ÷ 50/7
= 10×7/50
= 7/5
= 1.4
(i). [100-{80÷(20×2)}] +3
= [ 100-{80÷40}] +3
= [ 100-2] +3
= 98+3
= 111
(j). 80 + [ 10×{16-(8-4)}]
= 80 + [ 10×{16-4}]
= 80 + [10×12]
= 80 + 120
= 200
(k). [ { 22÷2×11+3}-{40÷10+3-5} ]
= [ {11×11+3} - {4+3-5} ]
= [ {121+3} - {7-5} ]
= [ 124 - 2]
= 122
(l). 22÷ [ 2+{12(14-4+10)÷12} ]
= 22 ÷ [ 2+{12(10+10)÷12} ]
= 22 ÷ [ 2+{12×20÷12} ]
= 22 ÷ [ 2+{12 × 5/3} ]
= 22 ÷ [ 2+20 ]
= 22 ÷ 22
= 1
(m). 9of600-{(14 of 650 - 2 of 50)÷3+4 of 250}
= 5400 - { ( 910 - 100) ÷3 +1000}
= 5400 - { 810÷3 +1000}
= 5400 - { 270+1000}
= 5400 - 1270
= 4130
(n). 12 [ { (9÷3)-(4÷2)} of 2 +(2-4-3)]
= 12 [ { 3-2} of 2 + -5]
= 12 [ 1 of 2 -5]
= 12 [ 2-5]
= 12[-3]
= -48
