To simplify a fraction, divide the numerator and the denominator by their GCF. Example: 30/42 The GCF of 30 and 42 is 6. 6 into 30 is 5 6 into 42 is 7 30/42 = 5/7
0.42 = 42/100 = 21/50
42/50 is 84%.
42 over 5 as a mixed number = 82/5
The least common multiple of 42 and 90 is 630. The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.
42/43
Oh, dude, 28 over 42 reduced to its lowest terms is like 2 over 3. You just divide both numbers by their greatest common factor, which in this case is 14. It's like simplifying a fraction, but way less exciting.
28/42 = 4/6 = 2/3
42/98 = 3/7
42 over 204 in lowest terms = 7/34
56 over 42 (56/42) in lowest terms is 4/3 or 11/3
10 over 42 in lowest terms = 5/21

2 and 1 over 3 or 2 1/3
21/42 = 1/2
28/42 is 2/3 in its lowest terms
