Answer:
2:5
Explanation:
In this question, we are writing a ratio for the given statement
We know that the worker uses: 5 loaves of wheat bread and 2 loaves of rye bread
Ratios are written in respective order, so we would write it as "value of rye bread" : "value of wheat bread"
Plug in:
2:5
We can't simplify the ratio, so that'll be your answer.
