1. 5m = 1.4kg 
   100m = ?kg

How many 5m does 100m contains?
That's 100 / 5 = 20m
For every 20m how many kg does it weights?
That's 20 * 1.4 = 28kg
100m of it weights 28 kilograms

2. I found it hard to solve work word problems, you can consult the internet for this.

3. 5,000.00 = 250.00
  40.000.00 = ?

How many 5k does 40k contains?
That's 40/5 = 8k
For every 8k, how many 250p is it equal to?
That's 8 * 250 = 2,000 pesos

4.-5. I don't know that, sorry. :(
