Question

1) 77:11 + (100 - 99) × 22) (15-3-10):7+ 20.​

Answer 1

1) 100-99=1
77:11=7
1•2=2
7+2=9

Answer 2

Let's break down the expression step by step:

1. 77:11 → This is the division of 77 by 11, which equals 7.

2. (100 - 99) × 22 → First, subtract 99 from 100, which equals 1. Then, multiply 1 by 22, resulting in 22.

3. (15-3-10):7 → First, subtract 3 from 15, which is 12. Then, subtract 10 from 12, which is 2. Finally, divide 2 by 7, resulting in approximately 0.2857.

4. Putting it all together: 7 + 22 + 0.2857 + 20 → Summing these values, we get approximately 49.2857.

So, the final result of the expression is approximately 49.2857.
