i'm not sure how to put it in rounded to two decimal places.

Vocaloid · Answer

left part is fine, but when you plug that into a calculator you get 1.405 not 1.045, and 1.405 properly rounded to 2 decimal places should be 1.41

KyledaGreat · Answer

i meant 1.405 my apologizes

Vocaloid · Answer

yeah, but since it asks for 2 decimal places you need to round up to 1.41
