To solve the problem of determining how many more millions of women were working in 1970 compared to 1960, we need to follow these steps:
1. Identify the number of millions of women working in 1960. Let's call this number [tex]\( \text{women}_{1960} \)[/tex].
2. Identify the number of millions of women working in 1970. Let's call this number [tex]\( \text{women}_{1970} \)[/tex].
3. Subtract the number of millions of women working in 1960 from the number working in 1970 to find the difference.
The formula to find the difference is:
[tex]\[ \text{Difference} = \text{women}_{1970} - \text{women}_{1960} \][/tex]
Given that the result of this calculation is 0, we can summarize it as follows:
[tex]\[ \text{Difference} = \text{women}_{1970} - \text{women}_{1960} = 0 \][/tex]
Therefore, there were 0 more millions of women working in 1970 than had been in 1960. This means the number of women working in both years was the same.
Given the multiple-choice options provided:
- 2 million
- 4 million
- 6 million
- 8 million
None of these options are correct based on the result.
The correct answer is:
None of the provided options are correct since there was no increase; the number of women working in both years was the same.
