Hey everyone! Today in class we were given questions from the textbook. I had to do question

**6**from 2.3.First you find the

**common denominator**. Sometimes when you**multiply both denominators**you can find the**, but that doesn't always work because you want the***common denominator***least common denominato**r. For example, in questions**b), d), and e)**If you multiplied both the denominators, the denominator would be a big number. So you have to find the**least common multiple.**The next step is, whatever you do to the bottom (denominator), you do to the top (numerator).

*Refer to a) Think

**how many times**does 3 go into 12? 4 times, so you have to**multiply both**the**numerator**and**denominator**by 4. (2 x 4 = 8) Also with the other fraction (3/4), you find**how many times**does 4 go into 12? 3 times, so you multiply the**denominator**and**numerato**r by 3.Then after you changed the fractions which are now equivalent fractions, (still referring to a) you minus (or add, depending on the question) the

**numerators.**(8-9= -1) and**keep**the**denominator**the same.In question

**e)**there are mixed fractions. One way to*change***mixed fractions**into**improper fractions**is by,**multiplying**the*denominator*by the*whole number*and**adding**the*numerator*to get the NEW numerator. Keep the denominator the same.In question

**f)**you can just take the whole numbers and fractions and separate them. First you do the whole numbers 1 + (-1) = 0. Then you do the fractions like you would normally do it.Sorry if this doesn't really make sense, I tried to explain it. And sorry for lack of colours, it doesn't work.
