From the pie chart, in 1960 women made up 33.4 percent = about 1/3 of the labor force

From the graph, the number of women in the labor force is about 22 million

~22 million is about 1/3 of the total labor force, $$y$$

$$22 = \frac{1}{3}y$$
$$(22)(3) = y$$
$$y$$= about 66 million

*OR
$$22 = .334y$$
$$\frac{22}{.334} = 65.87 = y$$
