# Roberto studied 3/5 hour every day for 7 days. How many hours did Roberto study in 7 days?

i believe it would be 4 1/5 hours

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
