Answer: A
Step-by-step explanation:
The pyramid's sides is twice as big so x is twice as big too
Let find the least of common multiple = LCM it’s for the denominators.
Multiple of the numerator then the denominator to get the denominators
Don’t forget to to add the numerator but leave the denominators the same
Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.
I can’t really see it but it looks like 1
