The answer is rounded to the nearest tenth.
Answer:
7/12
Step-by-step explanation:
To subtract fractions, you must make all of the fractions have a common denominator. We can set both of the denominators as 12. To achieve this, you must multiply both sides of 2/3 by 4. This will change the denominator of the fraction, while keeping the fraction equal to 2/3. Doing this will give us 8/12. Now we can subtract. Since the denominators are the same, we only subtract the numerators. Since 8-1 is 7, our answer is 7/12. The denominator does not change.
It would be 20, because 5 plus 4 is 9 and you can multiply 9 by 2 to get 18, 9 by 3 to get 27, and 9 by 4 to get 36, but you can't multiply anything by 9 to get to 20.
