List the factors.
1, 2, 3, 6, 7, 14, 21, 42
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The GCF is 6.
List the multiples.
42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462
60, 120, 180, 240, 300, 360, 420, 480
The LCM is 420.
100*42/60 = 70%
42 is 60% of 70
100*42/60 = 70%
the answer you are looking for is 70% because 60*.7=42 and .7 is 70% in decimal form to get this you do 42/60 (42 divided by 60)=.7 and .7 multiplied by 100%= 70%
1) listing method: { 1,2,3} rule method: {x| x is a positive whole number less than four} 2) listing method: { 2,4,6,8,....}. rule method: {x| x is a positive even number }
An easy method to find the LCM of two or more numbers is to list their multiples.Multiples of 42: 42, 84, 126, 168, 210, ... 7140Multiples of 51: 51, 102, 153, 204, 255, 306, ... 7140Multiples of 60: 60, 120, 180, 240, 300, 360, ... 7140The LCM of 42, 51 and 60 is 7140.
roster method is just like listing method
60-42 = 18
The LCM of 5 and 8 is 40. I don't know the listing method.
listing method , factor tree
100*42/60 = 70%
42 is 60% of 70
100*42/60 = 70%
42 subtracted by 60 = -18
the answer you are looking for is 70% because 60*.7=42 and .7 is 70% in decimal form to get this you do 42/60 (42 divided by 60)=.7 and .7 multiplied by 100%= 70%
1) listing method: { 1,2,3} rule method: {x| x is a positive whole number less than four} 2) listing method: { 2,4,6,8,....}. rule method: {x| x is a positive even number }
60/42 = 10/7
