first you have to get 3/5 to a decimal to make it easier to multiply. so you would do 5 times 20 and that would make your denominator 100.
100
if you times the denominator by 20, you have to do the same thing to the numerator so 3 times 20 is 60 so that's 60/100 which is 0.60 and that's equivalent to 3/5 and 6/10 and all that.so 0.60 times 10 is 6, so your coach runs 6 miles everyday. or you could do 10/1 times 3/5. hope that helped.
6 miles ;
Your coach runs 6 miles each day, which is calculated by multiplying the 5 3 mile you run by 10. This gives a total of 5 30 = 6 miles. In summary, coach runs 10 times your distance of 5 3 mile, resulting in 6 miles.
