Answer
1/2
step by step explanation
first you would have to find a common denominator which is 10
then convert 1/5 to something over 10 which is 2/10
after that you would subtract 3 7/10 by 3 2/10
3-3=0
7/10 - 2/10 is 5/10
5/10 can be simplified to 1/2 since they are both divisible by 5
Hoped that helped!
Have a nice day!
