Answer 1

(54 + a) : 2 = 40

54 + a = 40 × 2

54 + a = 80

a = 80 - 54

a = 26

(18 + b) : 3 = 30

18 + b = 30 × 3

18 + b = 90

b = 90 - 18

b = 72

(c + 74) : 4 = 20

c + 74 = 20 × 4

c + 74 = 80

c = 80 - 74

c = 6

(7 + d) : 5 = 10

7 + d = 10 × 5

7 + d = 50

d = 50 - 7

d = 43

(24 + e) : 3 = 30

24 + e = 30 × 3

24 + e = 90

e = 90 - 24

e = 66

820 : 4 - f = 148

205 - f = 148

f = 57

600 : 60 + g = 60

10 + g = 60

g = 60 - 50

g = 10

h - 640 : 2 = 507

h - 320 = 507

h = 507 + 320

h = 827

i + 707 : 7 = 416

i + 101 = 416

i = 416 - 101

i = 315

j + 999 : 9 = 902

j + 111 = 902

j = 902 - 111

j = 791
