Question

Thực hiện phép tính sau:

-1/16 - 1/15 =

Ai nhanh, đúng mk tick! giúp mk nha!!

Answer 1

\(-\frac{1}{16}-\frac{1}{15}\)

\(=-\left(\frac{1}{16}+\frac{1}{15}\right)\)

\(=-\frac{16+15}{16\times15}\)

\(=-\frac{31}{240}\)

Answer 2

31/240

đó bạn

Answer 3

\(-\frac{1}{16}-\frac{1}{15}=\frac{-15}{240}-\frac{16}{240}=\frac{-15-16}{240}=\frac{-31}{240}\)

Answer 4

\(\frac{-1}{16}\)-\(\frac{1}{15}\)

=\(\frac{-15}{240}\)-\(\frac{16}{240}\)

=\(\frac{-15-16}{240}\)

=\(\frac{-31}{240}\)
