Answer:Any number less than -13.
Step-by-step explanation:
If the number is real and rational and non-natural, this means that it can be any number in the negative number space.
Additionally, since the number has to be less than -13, then the number could be any number less than -13.
With all these things considered, the number is any number less than -13 that is real and rational.

Answer: £90
Step-by-step explanation:
Pip and Sara get some money. They share it in the ratio 5 : 4.
Pip gets £50 so what did Sara get:
Use direct proportion:
5 : 4
50 : x
5x = 200
x = 200/5
x = £40
Pip got £50 and Sara got £40.
Together they got:
= 50 + 40
= £90
299/9 is the correct answer
