We have to divide 9/10 by 3/12.
if we divide by a fraction, we can instead multiply by it's inverse:
so now we count:
so we can cut exactly 3 pieces!
The picture is very blurry
4.8 is not an integer. The notion of <em>prime factorization</em> is generally applied only to integers.
_____
You can find the prime factorization of its reduced improper fraction:
24/5 = (2×2×2×3)/5
This factorization can be useful when finding GCF or LCM of this number and other (proper or improper) fractions and/or integers.
K/3 +21 = 27
subtract 21 from both sides...
k/3 = 48
now multiply 48 and 3 to find k...
48 x 3 = 144
k=144
