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
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.The least common multiple of 2, 6, and 7 is 42.
0.42 = 42/100 = 21/50
42/50 is 84%.
The LCM refers to integers, not decimals.
42/43
28/42 = 2x14/3x14 = 2/3
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
42
10 over 42 in lowest terms = 5/21
140
2 and 1 over 3 or 2 1/3
21/42 = 1/2
28/42 is 2/3 in its lowest terms
