1. Set up a proportion:

* We know 1 ounce is equal to 28.21 grams.

* We want to find out how many ounces are in 61.65 grams.

This can be written as a proportion:

1 ounce / 28.21 grams = x ounces / 61.65 grams

2. Solve for x:

* Cross-multiply: 1 ounce * 61.65 grams = 28.21 grams * x ounces

* Simplify: 61.65 ounce-grams = 28.21 grams * x ounces

* Isolate x: x ounces = 61.65 ounce-grams / 28.21 grams

* Calculate: x ≈ 2.18 ounces

Therefore, there are approximately 2.18 ounces in 61.65 grams.
