Mia needs to separate 270 blue pens and 180 red pens into packs. each pack will have the same number of blue pens and the same number of red pens. what is the greatest number of packs she can make? how many red pens and how many blue pens will be in each pack?

we know that

Find the Greatest Common Factor (GCF)

The GCF is equal to------>

therefore

the answer part a) is

the greatest number of packs she can make is

Find the number of red pens in each pack

Divide the total number of red pens by the total number of packs

Find the number of blue pens in each pack

Divide the total number of blue pens by the total number of packs

therefore

the answer part b) is

There are in each pack

There are in each pack

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
