anonymous · Answer

find the multiple you need to get 5 to 10 which is 2 then multiply 4 and the 5 to get your new fraction 8/10 then you would subtract the 3/10's from there

anonymous · Answer

i also have to simplify it

anonymous · Answer

ohhh for that all you need to do is this 4/5 
                  3/10 
5 * 2 = 10 so that to turn 4/5 into the denominator 10 u need to mutiply the numerator and denominator of 4/5 by 2 to get your answer
