Answer:
3/5 + 4/7 =
Lcm = 35 so you divide it with the denominator and multiply with the numerator
first part will be 35 divide by 5 that's 7 multiply by 3 that's 21
second part will be 35 divide by 7 that's 5 times 4 is 20
Add the 20 and 21 together and you'll get 41 and divide it by 35
Answer will be 1.1714
