Band practice lasted 4/5 of an hour. 2/3 of that time was spent marching. how many minutes were they marching?

They were marching for 32 minutes.

Step-by-step explanation: If you multiply the 4/5 times by 60 minutes (1 hour), then you will get 48 minutes. 48 minutes is the time of the band practice. Once you get that, then multiply that by 2/3 to get the amount of minutes marching. Once you multiply 2/3*48, you will get 32, which is how many minutes they were marching during band practice.

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
