So u now that’s 3 times 5 is 15 so think of a number that 15 can divide into so x would be 3 cause 15 divided by 5 is 15
I got 20. Because it is multiplying you have to change it to division. So 15/1 x 3/5 but then you have to flip the second fraction so 15/1 x 5/3 which would equal 60/3 and 60/3 reduced by 3 (divid 3) would give you 20. Your answer is 20
