(34-(-51)):(95-78)=(34+51):(95-78)=85:17=5

(-28-(-49)):(47-68)=(-28+49):(47-68)=21:(-21)=-1

(58-85):(45-54)=-27:(-9)=3( при деление или умножение - на -=+)

(-42-24):(18-51) =-66:(-33)=2

72*(-16):153=-1152:153=-7 81/153=-7 9/17

34*(-72):153=-2448:153=-16

56*(-28):49=-1568:49=-32

Answer 3

Let's solve each of the given expressions step by step:

A) (34 - (-51)) : (95 - 78)

Step 1: Solve the inside of the parentheses first: 34 - (-51) = 34 + 51 = 85 95 - 78 = 17

Step 2: Divide the results: 85 : 17 = 5

B) (-28 - (-49)) : (47 - 68)

Step 1: Solve the inside of the parentheses first: (-28) - (-49) = -28 + 49 = 21 47 - 68 = -21

Step 2: Divide the results: 21 : (-21) = -1

C) (58 - 85) : (45 - 54)

Step 1: Solve the inside of the parentheses first: 58 - 85 = -27 45 - 54 = -9

Step 2: Divide the results: (-27) : (-9) = 3

D) (-42 - 24) : (18 - 51)

Step 1: Solve the inside of the parentheses first: (-42) - 24 = -66 18 - 51 = -33

Step 2: Divide the results: (-66) : (-33) = 2

E) 72 * (-16) : 153

Step 1: Multiply: 72 * (-16) = -1152

Step 2: Divide the result: -1152 : 153 = -8

F) 34 * (-72) : 153

Step 1: Multiply: 34 * (-72) = -2448

Step 2: Divide the result: -2448 : 153 = -16

G) 56 * (-28) : 49

Step 1: Multiply: 56 * (-28) = -1568

Step 2: Divide the result: -1568 : 49 = -32

So the solutions are:

A) 5 B) -1 C) 3 D) 2 E) -8 F) -16 G) -32
