Question

Bài 1:  Thực hiện phép tính sau:

\(c,\dfrac{12}{5}:\dfrac{16}{15}\)

\(d,\dfrac{9}{8}:\dfrac{6}{5}\)

 

 

Answer 1

12/5 : 16/15 = 9/4

9/8 : 6/5 = 15/16

Chúc bạn học tốt!! ^^

Answer 2

c, \(\dfrac{12}{5}:\dfrac{16}{15}=\dfrac{12}{5}.\dfrac{15}{16}=\dfrac{9}{4}\)

d, \(\dfrac{9}{8}:\dfrac{6}{5}=\dfrac{9}{8}.\dfrac{5}{6}=\dfrac{15}{16}\)

Answer 3

c. 12/5 : 16/15

= 12/5 . 15/16

= 9/4

 

d. 9/8 : 6/5

= 9/8 . 5/6

= 15/16

Answer 4

c: \(\dfrac{12}{5}:\dfrac{16}{15}=\dfrac{12}{5}\cdot\dfrac{15}{16}=\dfrac{240}{80}=3\)

d: \(\dfrac{9}{8}:\dfrac{6}{5}=\dfrac{9}{8}\cdot\dfrac{5}{6}=\dfrac{45}{48}=\dfrac{15}{16}\)
