Several calculation problems (simple calculation)

(108 + 45 and 72 / 73) divided by 9, 12 and 3 / 4 divided by 1 and 1 / 5 + 5.25 * 5 / 6

95 / 97 * 63 = 5985 / 97 = (61 * 97 + 68) / 97 = 68 (8 + 1 / 2) + 6.85 + 1.6 + (2 + 3 / 20) = 8.5 + 6.85 + 1.6 + 2.15 = (8.5 + 1.6) + (6.85 + 2.15) = 10.1 + 9 = 19.1 [108 + (45 + 72 / 73)] / 9 = 108 / 9 + 45 / 9 + (72 / 73) / 9 = 12 + 5 + 8 / 73 = 17 + 8 / 73 = 17 and 8 (12 + 3 / 4) / (1

Need simple calculation, please everyone to fast

（1）9.81X0.1+0.5X98.1+0.049X981
=9.81x0.1 + 5x9.81 + 4.9x9.81
=9.81x(0.1+5+4.9)
=9.81x10
=98.1
（2）7.8÷[(9-8.98)X2.5}
=7.8÷(0.02x2.5)
=7.8÷0.05
=7.8x20 (simple calculation here is △ 0.05, i.e. △ 1 / 20, i.e. X20)
=156

1: First of all, you need to know the calculation formula of 11 × 11 type problems, such as 11 × 11 = 121, 111 × 111 = 123211111 × 1111 = 1234321. I believe you have seen the law, then the first problem is well solved, 222222 × 5555 = 2 × 111111 × 5 × 111111 = 2 × 5 × 111111 × 111111 = 10 × 123

It takes 10 days to build a highway, but it takes less than 2 days. It is known that the actual construction is 1.5 kilometers more than the original plan. How many kilometers is the highway long?

The first question on the second floor is wrong. How can there be an extra 2? There is only one 2

Calculation: (1) 1002 - (2522-2482); (2) 39.82-2 × 39.8 × 49.8 + 49.82

(1) Original formula = 1002 - (252 + 248) (252-248) = 10000-500 × 4 = 8000; (2) original formula = (39.8-49.8) 2 = 100
