Question

1)960:3=? 780:6=? 945-9*5:3=? 600+6*7:2=? (200+450):5=? (720-120):3=?

Answer 1

960:3=320   780:6=130   945-9*5:3=945-45:3=945-15=930  

600+6*7:2=600+42:2=600+21=621   (200+450):5=650:5=130

(720-120):3=600:3=200

Answer 2

1)320, 2)130, 3)930 4)2121 5)130 6) 200

Answer 3

Let's solve each of these expressions step by step:

1. 960:3 = ? To divide 960 by 3, simply perform the division operation: 960 ÷ 3 = 320

2. 780:6 = ? To divide 780 by 6: 780 ÷ 6 = 130

3. 945-9*5:3 = ? Follow the order of operations (PEMDAS/BODMAS): First, perform the multiplication: 9 * 5 = 45 Then, perform the division: 45 ÷ 3 = 15 Finally, subtract from 945: 945 - 15 = 930

4. 600+6*7:2 = ? Again, follow the order of operations: First, perform the multiplication: 6 * 7 = 42 Then, perform the division: 42 ÷ 2 = 21 Finally, add to 600: 600 + 21 = 621

5. (200+450):5 = ? Start with the addition inside the parentheses: 200 + 450 = 650 Then, perform the division: 650 ÷ 5 = 130

6. (720-120):3 = ? Start with the subtraction inside the parentheses: 720 - 120 = 600 Then, perform the division: 600 ÷ 3 = 200

So the solutions to the given expressions are:

1. 960:3 = 320
2. 780:6 = 130
3. 945-9*5:3 = 930
4. 600+6*7:2 = 621
5. (200+450):5 = 130
6. (720-120):3 = 200
