let me explain how you do this  if for 1 day he studies 3/5s of an hour. And the question is asking for 7 days then all we have to do is multiply 3/5s times 7! Ill guide you through the math;)  3                                                               3         7     ----   x   7  we can also write it like this   ---   x   ---   lets use this one:)    5                                                               5         1 but now our next step is to multiply across!    3         7   =   3 x 7 = 21  ---   x  ----                       so our new fraction issssss  5         1   =   5 x 1 = 5   21 -----   and since 5 goes into 21 four times and 2 is left over this is how         5     much he studied in 7 days  4.2 hours or as a fraction...     1 4 ----     5 answer? 4.2 hours studied :D have a good one and  MARK ME BRAINLIEST!!:D thxx bye
