1pt How do you know if a fraction is in simplest form?

1pt When the numerator and the denominator have a GCF of 1 which means that they are relatively prime.

2pt What are the two methods for adding and subtracting mixed numbers?

2pt Metod1: leave as mixed numbers and find LCD and simplify Method2: write as improper fractions first then find LCD and simplify

3pt Whether you are adding/ subtracting fractions, improper fractions or mixed numbers with unlike denominators what is the first thing you need to find?

3pt You need to find the LCD or LCM of the denominators

4pt Luke’s answer: 5/2 Molly’s answer: 29/15 Look at the two answers written below for the expression 7/3 -2/5= Who is correct? Who is wrong and why?

4pt Molly is correct. Luke subtracted the numerator and the denominator and did not find common denominator

5pt Why do we have to multiply the numerator and the denominator by the same number when writing equivalent fractions?
