When you have a mixed number like 8 1/7, it represents a whole number part (8) and a fractional part (1/7). The goal is to find out how many one-seventh parts are in the entire quantity.
1. Whole Number Part (8): This means you have 8 whole units. Each whole unit can be broken down into 7 parts (sevenths).
2. Fractional Part (1/7): This means you have an additional 1 part out of 7 parts that make up a whole.
So, let's start by looking at the whole number part:
- 8 whole units * 7 parts each = 56 parts
Now, let's consider the fractional part:
- 1 part out of 7 parts
Adding these two parts together:
- 56 parts (from the whole number) + 1 part (from the fractional part) = 57 parts
So, in the mixed number 8 1/7, there are a total of 57 one-seventh parts. This is why the correct answer is (d) 57.
