4 ft=?in
what you mean by 4ft=it's 48 in
that not my question . i want to know how to do the other problem as well on the meant for the following number?
33,41,37,27,32,?
mean is the average
add all the numbers to get the sum
divide the sum by the number of numbers you are adding.
33 + 41 + 37 + 27 + 32 = 170
since there are 5 numbers, you divide the sum by 5, to get the mean
170/5 = 34
the mean is 34
LCM
6, 4, 8
LCM is 24
how I was taught
factor each into prime numbers
6 = 2 x 3
4 = 2 x 2
8 = 2 x 2 x 2
write down the most times each factor was used in each factorization
2-was used at most 3 times
3-was used at most 1 time
LCM = (3x2)times (1x3)
LCM = 6x3 = 24
or,
2 x 2 x 2 x 3 = 24
33 + 41 + 37 + 27 + 32 = 170
170 / 5 = 34
The mean (or average) is 34.
(LCM) for 6,4,and 8?
Which of these numbers is also divisible by 6 and 4?
8, 16, 24, 32, 40
4 feet = 4 x 12 in/ft = 48 inches
from above, this should say
write down the most times a factor was used within one factorization
