Here's how to subtract 1/10 from 7/10:
Since our denominators match, we can subtract the numerators.
7 − 1 = 6
So the answer is:
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Let's try dividing by 2 again...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
No good. 5 is larger than 3. So we're done reducing.There you have it! The final answer is:
