a)

b)

Step-by-step explanation:

a) Given the ratio of the weight of vegetables sold to the weight of fruits sold:

In order to calculate how many times the weight of vegetables sold is the weight of fruits sold, we must dive 144 by 45:

Now we can make the conversion from improper fraction to mixed number:

- When we divide 16 by 5, we get a quotient of 3. This will be the whole number part.

- The remainder we get is 1; this will be the numerator of the fraction.

- The denominator does not change.

Then we get:

Therefore, the weight of the vegetables sold is times the weight of fruits sold.

b) When we add 45 and 144, we get this total weight:

Then, in order to find what fraction of the total weight of vegetables and fruits sold is the weight of vegetables sold, we can divide 45 by 189:
