60.4 .........

Answer 2

92:2320-72:1210 =

First, let's simplify the expressions inside the parentheses:

• 72:12 = 6
• 92:23 = 4

Substituting these values, we have:

420 - 610

= 80 - 60

= 20

98:75-203 =

98:7 = 14

Substituting this value, we have:

145 - 203

= 70 - 60

= 10

40*20:5-(88:22+6) =

First, let's simplify the expressions inside the parentheses:

• 88:22 = 4
• 6 = 6

Substituting these values, we have:

40*4 - (4+6)

= 160 - 10

= 150

66:22*20+8:20 =

First, let's simplify the expressions inside the parentheses:

• 66:22 = 3
• 8:20 = 0.4

Substituting these values, we have:

3*20 + 0.4

= 60 + 0.4

= 60.4

Therefore:

92:2320-72:1210 = 20 98:75-203 = 10 4020:5-(88:22+6) = 150 66:2220+8:20 = 60.4
