1) 60:2?20*3-100:2=2)50*2?100:5+40*2=3)100:2?80:2+90:3=

Answer 1

1)60:2+20*3-100:2=40
2)50*2-100:5+40*2=160
3)100:2+80:2+90:3=120

Answer 2

1) 60/2=30; 20*3-100/2=10
30>10
2)50*2=100; 100/5+40*2=100
100=100
3) 100/2=50; 80/2+90/3=70
50<70

Answer 3

1) 60:2?20*3-100:2 =

Let's break down the expression step by step:

First, we need to perform the division operation 60:2, which is equal to 30.

Next, we have the multiplication operation 20*3, which equals 60.

Now, we subtract the result of the first operation (30) from the result of the second operation (60). So, 60 - 30 = 30.

Finally, we perform the division operation 100:2, which is equal to 50.

Therefore, the final result is 2.

2) 50*2?100:5+40*2 =

Again, let's break down the expression step by step:

First, we perform the multiplication operation 50*2, which equals 100.

Next, we perform the division operation 100:5, which is equal to 20.

Then, we perform the multiplication operation 40*2, which equals 80.

Finally, we add the results of the previous two operations (20 + 80) to get 100.

Therefore, the final result is 100.

3) 100:2?80:2+90:3 =

Now, let's break down the expression step by step:

First, we perform the division operation 100:2, which equals 50.

Next, we perform the division operation 80:2, which is equal to 40.

Then, we perform the division operation 90:3, which equals 30.

Finally, we add the results of the previous two operations (40 + 30) to get 70.

Therefore, the final result is 70.

To summarize:

1) 60:2?20*3-100:2 = 2 2) 50*2?100:5+40*2 = 100 3) 100:2?80:2+90:3 = 70
