7. Find the LCM or Least Common Multiple of the two denominators. 12 divided by 4, multiplied by 3 is equal to 9 then the numerator is 9. After that, 12 divided by 3, multiplied by 1 is equal to 4. Add these numerators and you'd have a denominator of 12. The answer is an improper fraction, so you have to convert it into a mixed fraction by dividing these two.
8. Find also the LCM of these two denominators. The LCD is 9, so 9 divided by 9 is equal to 1 then multiply by 6. The answer will be 6. Same method goes for the second and the answer is 6/9. The fraction is improper because the numerator is way bigger than denominator. Divide these two and the answer will be 1 3/9. Find the lowest term and the answer would be 1 1/3 because you divided the numerator and denominator by 3.
9. These are similar fractions because it they have similar denominator. Consequently, your answer would be 4/5.
10. Subtract the numerators and find the lowest term. 4 divided by 2 is equal to 2 then 6 divided by 2 is 3.
