6x10=60m^2
2x1.5=3m^2
Pi x 2^2=12.566m^2
60-3-12.566=44.433
44.433/10=4.43
So around 5 bags
5 x4x60=£23
The HCF is the highest common factor of two numbers.
By definition, if two numbers are coprime, they have no common factors other than 1.
So, the highest (and only) common factor of two coprime numbers is 1.
5n+3/4n=2
20n+3n/4=2
23n/4=2
23n=8
n=8/23
Is this question lacking information? Because we don't know how much one pound costs.
