Find a ratio equivalent to 12/21 with lower terms
2 answers:
Here we are given the ratio 12 / 21.
In order to find its equivalent ratio with lower terms , we have to find common factor of 12 and 21 by which we can divide both the numbers.
So factors of 12 are 1, 2 ,3, 4.
Factors of 21 are 1, 3, 7.
So our common factor is 3 here.
dividing both numerator and denominator by 3 we have:
12 divided by 3 equals 4 and 21 divided by 3 equals 7.
So our new ratio becomes 4/7

Option B: 1088 is the next term in the geometric sequence.
Explanation:
The sequence is
We need to determine the next term.
To determine the next term, let us find the common ratio between the terms.
Thus, the common ratio is
And the given sequence is a geometric sequence.
To determine the next term in a geometric sequence, we always multiply the common ratio to the current term.
Hence, the current term is 272 and the common ratio is 4.
Next term = Current term × Common ratio
Thus, the next term of the geometric sequence is 1088
Therefore, Option B is the correct answer.
