Answer:
2 batches
Step-by-step explanation:
1. State the given;
<u>Convert to improper fractions;</u>
1 1/4 blackberries
5/4 blackberries
<u>Simplify;</u>
Twice as many blueberries;
5/4 *2
10/4
5/2
2. Find the total amount of berries;
<u>Simplify;</u>
blackberries + blueberries
= 5/4 + 5/2
*note; convert to like denominators
= 5/4 + 10/4
= 15/4
3. Divide by the amount that the recipe calls for;
Total / required
15/4 / 3/4
*note; dividing by a fraction is the same as multiplying by the fraction's reciprocal
15/4 * 3/4
45/16
*note; convert to a mixed number
2 13/16
Remember, for the sake of the problem, one can only make a full recipe, hence the answer is 2.
