The Fernando family spends $800 per month on rent. If this is 15% of their monthly budget, then what is their monthly budget?

Step-by-step explanation:

So you have 800 per month on rent and that 15%

given 100-15=85%

so how many times does 85 divide by 15?

85/15=5.66

so multiply that factor by 800 and add 800 to get the monthly budget.

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
