1 in 10 equals 0.1100, 3 in 10 equals 0.31000, and 5 in 100 equals 0.005. What's the rule

1 in 10 equals 0.1100, 3 in 10 equals 0.31000, and 5 in 100 equals 0.005. What's the rule

Your second should be 0.03
The rule is to increase the denominator by 10
The numerator increases in odd sequence

（3-3/10-3/100-3/1000.-3/10000000000）/0.3,
We should use a simple method and explain how to calculate it by the way

Divide each item in brackets by 0.3, and then divide the denominator into the same denominator as the last item. The first item subtracts the sum of all the following items to get the solution, 888888889

9 / 4x + 7 / 2 (1000-x) = 400? This morning!

9/4x+(7000-7x)/2=400
9/4x+3500-7/2x=400
9/4x-14/4x=400-3500
-5/4x=-3100
x=2480

Solution equation: 2 × 1000 x 2.5 × 1000 (20-x) = 45000
2×1000X+ 2.5×1000(20-X)=45000

2x1000x2.5x1000(20-x)=45000
100000000-20x =45000
20x =99955000
x =4997750

(x-160): (1000-x) = 5:2

(x-160)*2=(1000-x)*5
2x-320=5000-5x
7x=5320
x=760

Solving equation x / 5 + 6950-x / 8 = 1000
The answer is 1750, but I can't figure it out

8x +5(6950-x) =40000
8x -5x = 40000 - 5*6950
3x =5250
x = 1750
