Step-by-step explanation:
to find a common denominator, you have to find a number that "works" with every other number.
for example, say you have
2/4 and 8/12
First you need to find the common factor between 4 and 12, so list all your fours
4, 8, 12, 16, 20
Now list all your twelves
12, 24, 36, 48, 60
to find the common factor you look at both your list of numbers and find one that's the same, sometimes it takes a long list of numbers to find the common factor, but you will run into one.
So by looking at our list we see that 4 and 12 share the common factor of 12. but since 8/12 already has a denominator of 12, we are going to leave it alone.
now think about what you would multiply 4 by, to get to 12. The answer is
4 x 3 = 12
to make the numerator correct, you multiply it by the same number you did 4, so since your faction is 2/4 you should do 2 x 3 = 6
now you have your answer,
2/4 and 8/12 turns into
6/12 and 8/12
and that's how you find it, let me know if you have questions :)
Answer:
21
Step-by-step explanation:
3 times 7 is 21
7 times 2 is 14 and 3 doesn't go into that!
7 times 1 is 7 and 3 doesn't go into that either!
Can I have brainliest please, if not that's ok. :)
Answer:
The difference in 7,301,985 is that the 7 is in the Millions place. And the difference in 7,338 is that that 7 is in the thousands place.
Hope this helps ☝️☝☝
Answer:
-13734
Step-by-step explanation:
We're going to use pemdas for this equation.
Since there are no parenthesis we move on to exponents, which we do have, so we would cube 24, which gets us 13,824.
Next we subtract 90 from 13,824 which gives us our answer of -13,734
