\(\frac{3}{5}\times\frac{8}{9}\)

Answer 1

làm sao để ghi được phân số vậy, chỉ mk với

Answer 2

45/7 : 3/5 + 1 = 82/7

3/5 x 8/9 = 8/15

Answer 3

\(\frac{45}{7}:\frac{3}{5}+1\)

\(=\frac{75}{7}+1\)

\(=\frac{82}{7}\)

\(\frac{3}{5}\times\frac{8}{9}\)

\(=\frac{24}{45}\)\(=\frac{8}{15}\)

Ủng hộ tk Đúng nhé ! ^^ 

Answer 4

\(\frac{45}{7}:\frac{3}{5}+1=\frac{75}{7}+1=\frac{82}{7}\)

\(\frac{3}{5}x\frac{8}{9}=\frac{8}{15}\)

~~ tk mk nha ~~ T_T

Xin các bn đó Y_Y

Làm ơn đi Y_Y

Answer 5

\(\frac{45}{7}\div\frac{3}{5}+1\)

\(=\frac{45}{7}\times\frac{5}{3}+3\)

\(=\frac{75}{7}+1\)

\(=\frac{82}{7}\)

\(\frac{3}{5}\times\frac{8}{9}=\frac{3\times8}{5\times9}=\frac{24}{45}\)

Answer 6

75/7+1= 82/7

3/5 x 8/9 = 8/15

tk mk nha

Answer 7

a) 45/7 : 3/5 + 1

=  45/7 x 5/3 + 1

=  75/7 + 1

= 75/7 + 7/7

= 82/7

b) 3/5 x 8/9

= 8/15

Answer 8

\(\frac{45}{7}:\frac{3}{5}+1=\frac{45}{7}\times\frac{5}{3}+1=\frac{225}{21}+1=\frac{82}{7}\)

\(\frac{3}{5}\times\frac{8}{9}=\frac{8}{15}\)
