Answer:
Step-by-step explanation:To rewrite 4/6 : 1/3 as a unit rate, we need to first find a common denominator for the fractions. The least common multiple of 6 and 3 is 6, so we can use this as the common denominator.
We can then rewrite the fractions as follows:
4/6 : 1/3 = (4/6) * (3/3) : (1/3) * (2/2)
Simplifying, we get:
2/3 : 2/3
This is a unit rate, with a value of 2/3.
