Question

8/15 : 2/11 +2/15 :2/11

Answer 1

\(\frac{8}{15}:\frac{2}{11}+\frac{2}{15}:\frac{2}{11}\)

\(=\frac{2}{11}:\left(\frac{8}{15}+\frac{2}{15}\right)\)

\(=\frac{2}{11}:\frac{2}{3}\)

\(=\frac{2}{11}\times\frac{3}{2}\)

\(=\frac{3}{11}\)

tíc mình nha

Answer 2

( 8/15 + 2/15 ) : 2/11 = 2/3 x 11/2

                              =      3/11

Answer 3

=3/11

Answer 4

\(\frac{8}{15}:\frac{2}{11}+\frac{2}{15}:\frac{2}{11}=\left(\frac{8}{15}+\frac{2}{15}\right):\frac{2}{11}\)

                                   \(=\frac{2}{3}:\frac{2}{11}\)

                                   \(=\frac{2}{3}x\frac{11}{2}\)

                                     \(=\frac{11}{3}\)
