Volume 1, Reading 13, Example 2

When I do that math out I don’t get -0.0254. All the numbers seem right but that doesn’t come out.

1.0145{(270/360)/(1.0487(270/360))}(0.0141-0.0487)= -0.03347?

(1.0145)(.75/.786525)(-0.0346) is what it should be no? Doesn’t that equal - 0.033471632? Yet the answer is B. - 0.0254

I’m sure I’m doing something really stupid, could someone just enlighten me quickly?
