Question 1017521
There are two requirements this number has to meet. We'll focus on the second one first. If you add one to the denominator, the fraction=one half. There are many options for this one, but it also has to meet the first requirement. Here are some options for the second requirement: If the fraction were 1/1, adding 1 to the denominator will make it 1/2, but that number doesn't meet the first requirement because adding one to the numerator and subtracting one from the denominator would make it 2/0 which is incorrect for two reasons: 1. It's undefined. The denominator of a fraction can't be 0. 2. 2/0 is not 1.
If the fraction were 2/3, it would meet the second requirement because it would become 2/4 which equals 1/2. However it does not reach the first requirement because it would become 3/2 which does not equal 1. The next option is 3/5. If you add 1 and 5, it becomes 6 and 3/6=1/2. It also meets the first requirement because 3+1=4 and 5-1 is 4 and 4/4=1
