The largest number that goes into both (the greatest common factor) is 4. 16/4=4 60/4=15
The LCM of 60 and 21 is 420
5 and 15 go into 60 & 75.
15 / 0.6 = 25 Therefore, 15 is 60 percent of 25.
4 goes into 60 15 times.
21/60 - 1/15 = 17/60 To subtract fractions, make them have the same denominator (bottom number) by converting them to equivalent fractions (usually with the lowest common multiple of the denominators) and then subtract the numerators (top numbers). So for 21/60 - 1/15: lcm(15, 60) = 60: 21/60 = 21/60 1/15 = 4/60 ⇒ 21/60 - 1/15 = 21/60 - 4/60 = 17/60
1, 3, 5 and 15
The largest number that goes into both (the greatest common factor) is 4. 16/4=4 60/4=15
The biggest number that goes into 60 evenly is 60.
The LCM of 60 and 21 is 420
60 ÷ 4 = 15
60 ÷ 15 = 4 times
not by a whole number 15 x 4 = 60 15 x 5 = 75 63/15 = 21/5 = 42/10 = 4.2
Designate the unknown number by x. Then (60 %)x = 21, or 0.6x = 21, or x = 35
5 and 15 go into 60 & 75.
900 divided by 60 is 15. So, 60 goes into 900 15 times.
15 / 0.6 = 25 Therefore, 15 is 60 percent of 25.
