Answer:
Explanation:
To get the LCM in the denominator:
1/2 x 9/9 = 9/18
3/9 x 2/2 = 6/18
9/9 and 2/2 both equal 1, so multiplying these fractions by ny number will result in the same number since any number times 1 is the same number.
9/18 - 6/18 = 3/18
Simplifying this answer:
3/18 = 1/6 because both the numerator and denominator are both multiples of three and are divisible by three.
The answer is 1/6.
