48: 6:2 48-6-2
54 - 6 + 72-9
54: 6 + 72:9​

Answer 1

a). 3 + 2 + 5 = 5 + 5 = 10

3 × 2 × 5 = 6 × 5 = 30

10 < 30

b). 7 + 9 - 12 + 48 = 16 - 12 + 48 = 4 + 48 = 52

7 × 9 - 12 + 48 = 63 - 12 + 48 = 51 + 48 = 99

52 < 99

c). 48 : 6 : 2 = 8 : 2 = 4

48 - 6 - 2 = 42 - 2 = 40

4 < 40

d). 54 - 6 + 72 - 9 = 48 + 72 - 9 = 120 - 9 = 111

54 : 6 + 72 : 9 = 9 + 8 = 17

111 > 17
