Question

thực hiện phép tính

\(\frac{7}{19}.\frac{8}{11}+\frac{7}{19}.\frac{3}{11}+\frac{12}{19}\)

Answer 1

\(=\frac{7}{19}.\left(\frac{8}{11}+\frac{3}{11}\right)+\frac{12}{19}\)

\(=\frac{7}{19}.1+\frac{12}{19}\)

\(=1\)

Answer 2

\(\frac{7}{19}\).\(\frac{8}{11}\)+\(\frac{7}{19}\).\(\frac{3}{11}\)+\(\frac{12}{19}\)

=\(\frac{7}{19}\).1+\(\frac{12}{19}\)

=1
