Step 1Since our denominators match, we can subtract the numerators. 7 − 1 = 6 So the answer is:

||||||||||||||||||
Step 2Last 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:
