Question

Perform each of the following conversions, being sure to set up clearly the appropriate conversion factor in each case.

2.23 m to yards

Am I supposed to round the answer? I don't think I am, but the answer I get is insanely large.

Answer 1

Chemistry?

A meter and a yard are almost the same length.

1 meter = 1.0936133 yards

2.23 * 1.0936 = 2.4716 = 2.47

2.23 meters = about 2.47 yards

Answer 2

I'd round 2.47 to 2 1/2 yards.

Answer 3

Yes, you should round the answer. To how many places? You started with 2.23 m which is three significant digits; therefore, you may have three s.f. in the final answer. Here is what your prof wants. The part in parentheses (1 yard/1.0936 m) is the conversion factor mentioned in the problem.
2.23 m x (1 yard/1.0936 m) = 2.4387 yards which would round to three s.f. as 2.44 yards.

Answer 4

DrBob is right. It's 2.4387 yards or 2.44 yards.
