Answer
not sure but 1 : 21
Step-by-step explanation:
Change values to whole numbers.
Convert the whole number 9 to a fraction with 1 in the denominator.
We then have:
3/7 : 9 = 3/7 : 9/1
Convert fractions to integers by eliminating the denominators.
Our two fractions have unlike denominators so we find the Least Common Denominator and rewrite our fractions as necessary with the common denominator
LCD(3/7, 9/1) = 7
We now have:
3/7 : 9 = 3/7 : 63/7
Our two fractions now have like denominators so we can multiply both by 7 to eliminate the denominators.
We then have:
3/7 : 9 = 3 : 63
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 3 and 63 is 3
Divide both terms by the GCF, 3:
3 ÷ 3 = 1
63 ÷ 3 = 21
The ratio 3 : 63 can be reduced to lowest terms by dividing both terms by the GCF = 3 :
3 : 63 = 1 : 21
Therefore:
3/7 : 9 = 1 : 21
