Elaine has a longer piece of wire. You know because if u add a zero to the end of her number it'll be 2.160 and since the whole numbers are the same, you look at the numbers after the decimal which are .061 or .160 (0 are worth nothing but it helps when comparing) and 160> 061 (u don't have to use the decimal in this situation to compare) so 2.160 > 2.061 Hope this makes sense.
