Answer:
To subtract fractions, we need to have a common denominator. The least common multiple of 5 and 10 is 10. We can convert 3/5 to 6/10 by multiplying both the numerator and denominator by 2. Now, we can subtract 6/10 from 9/10 to get 3/10.
To see why 3/10 is approximately equal to 1/2, we can simplify 3/10 by dividing both the numerator and denominator by 3. This gives us 1/3.33. Since 3.33 is close to 3, we can approximate 1/3.33 as 1/3, which is approximately equal to 1/2. Therefore, 9/10 - 3/5 is approximately equal to 1/2.
