Question

18:(2* 3)= 18:2:3 = (18:20:3 = (18:3):2 160 : (4*10)=810 : (30 * 3)=420:(2* 3)=480 : (20*4)​

Answer 1

160:40=4
810:90=9
420:6=70
480:80=6
18:6=3
18:2:3=3
18:20:3=0,3
18:3):2=3

Answer 2

Let's break down the calculations step by step:

1. 18:(2*3) = 18:6 = 3

Here, we first evaluate the expression inside the parentheses, which is 2*3 = 6. Then we divide 18 by 6 to get the result 3.

2. 18:2:3 = (18:2):3

In this case, we have a chain of divisions. First, we divide 18 by 2 to get 9, and then we divide 9 by 3 to get the final result of 3.

3. 160 : (4*10) = 160 : 40 = 4

Here, we calculate the expression inside the parentheses, which is 4*10 = 40. Then we divide 160 by 40 to obtain the result 4.

4. 810 : (30 * 3) = 810 : 90 = 9

Similar to the previous step, we evaluate the expression inside the parentheses, which is 30*3 = 90. Then we divide 810 by 90 to get the result 9.

5. 420 : (2 * 3) = 420 : 6 = 70

In this case, we calculate the expression inside the parentheses, which is 2*3 = 6. Then we divide 420 by 6 to obtain the result 70.

6. 480 : (20 * 4) = 480 : 80 = 6

Similarly, we evaluate the expression inside the parentheses, which is 20*4 = 80. Then we divide 480 by 80 to get the result 6.

To summarize:

• 18:(2*3) = 3
• 18:2:3 = 3
• 160 : (4*10) = 4
• 810 : (30 * 3) = 9
• 420 : (2 * 3) = 70
• 480 : (20 * 4) = 6
