In martin’s class of 20 students, 4 students report that social studies is their favorite class and 75% of the students report that pe is their favorite class. show your work to explain how to determine whether more students prefer social studies or pe. this needs to be written in an expression

Well, we know the total amount of students in the class is 20.  4 of them prefer SS, and 75% of them prefer PE.

now, if we take 20 to be the 100%, what is 4 off of it in percentage?



so, we know 20% prefer SS, and 75% prefer PE, well, notice the percentages, is clear that 20% < 75%

if we make the total class say hmmm "x", then 20% of x is (20/100) * x, or 0.2x, and 75% of x is (75/100) * x, or 0.75x, thus

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
