\(\frac{11}{15}\cdot\frac{6}{7}+\frac{11}{15}\cdot\frac{8}{7}\)
\(=\frac{11}{15}\cdot\left(\frac{6}{7}+\frac{8}{7}\right)\)
\(=\frac{11}{15}\cdot2=\frac{22}{15}\)
Chú ý dấu " \(\cdot\) " là dấu nhân
11/15 x 6/7 + 11/15 x 8/7
= 11/15 x (6/7 + 8/7)
= 11/15 x 2
= 22/15.
Mik ko chắc lắm nhé !
11/15 × 6/7 + 11/15 × 8/7
= 11/15x (6/7+8/7)
= 11/15x2
= 22/15
~Hok tốt~
\(\frac{11}{15}.\frac{6}{7}+\frac{11}{15}.\frac{8}{7}\)
\(=\frac{11}{15}.\left(\frac{6}{7}+\frac{8}{7}\right)\)
\(=\frac{11}{15}.\frac{14}{7}\)
\(=\frac{11}{15}.2=\frac{22}{15}\)
Chúc bạn học tốt
lấy 15+15[11+11]
11/15×(6/7+8/7)
11/15×2/1
22/15
Dạng toán: Một số nhân với một tổng
\(=\frac{11}{15}\times\frac{6}{7}+\frac{11}{15}+\frac{8}{7}\)
\(=\frac{11}{15}\times\left(\frac{6}{7}+\frac{8}{7}\right)\)
\(=\frac{11}{15}\times\frac{2}{1}\)
\(=\frac{22}{15}\)
#z
11/15 x 6/7 +11/15 x 8/7
=11/15 x (6/7 + 8/7)
=11/15 x 14/7
=11/15 x 2
=22/15
11/15 . 6/7 + 11/15 . 8/7
= 11/15 . ( 6/7 + 8/7 )
= 11/15 . 14/7
= 11/15 . 2
= 22/15
