Multiples : these are what we get after multiplying a number by an integer (not a decimal or fraction)
Example : 6 * 1 = 6......6 * 2 = 12.....6 * 3 = 18......so 6,12, and 18 are multiples of 6.
factors : these are what we multiply by to get a number
Example : 1 * 6 = 6.....so 1 and 6 are factors of 6....2 * 3 = 6 ...so 2 and 3 are also factors of 6
==============================
problem 1 : Look at ur clues...each number is less then or equal to 12....this right here eliminates D because of the 15. The greatest common factor of the 2 numbers is 2....and this eliminates B because if it has a factor of 2, it has to be an even number. So that leaves us with :
A. 6 and 10
C. 10 and 12
last clue....they have a least common multiple of 60...this means that ur 2 numbers cant have any other common multiples until 60.
6 * 10......both are multiples of 60...however, they are also both multiples of 30...so 60 is not the least common multiple of 6 and 10, it is 30.
Therefore, ur answer is C. 10 and 12....with the LCM of 60, LCF of 2 and < or = to 12
===================
problem 2 : GCF (greatest common factor) of 42 and 84
factors of 42 : 1,2,3,6,7,14,21,42
factors of 84 : 1,2,3,4,6,7,12,14,21,28,42,84
therefore, the GCF of these 2 numbers is 42

Answer:
Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
Step-by-step explanation:
Given:
Speed = 5.5 km/hr
Distance = 82 km
Let time be represented as 'x'.
We need to find the number of hours required to travel 82 km.
We know that Distance can be calculated by the product of Speed and time.
Framing above sentence in equation form we get;
Distance = Speed × Time
Substituting the given value we get;
Hence The expression for number of hours is
Solving the equation to find the value of x we get;
Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
9x10-8 is about 4.5 times larger than 3x10-12
First solve the equations
9*10-8
90-8
(82)
3*10-12
30-12
(18)
Divide 82/18= 4.5
