What does 3 2/5 - 3/4 equal? quick and explain why 15 points

The answer is 2 3/20 because if you want to subtract the fractions, the denominators must be the same. both can go into 20, so 2/5 becomes 8/20 and 3/4 becomes 15/20. now its 3 8/20 - 15/20. since you cant subtract like that, you must borrow from the whole number. 3 becomes 2 and 8/20 becomes 18/20. now its 2 18/20 - 15/20. you can do that now, which the answer comes out as 2 3/20.

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.
