7/5-6/5:3

tim y

y*6/7=3/4+2

     AI TRA LOI DUNG THI MINH TIK CHO

 

Answer 1

7/5 -6/5:3=7/5-2/5=1

yx6/7 = 3/4+2

y x 6/7 =11/4

y          = 11/4:6/7

y            =77/24

Answer 2

Bài 1:

7/5 - 6/5 : 3

= 7/5 - 2/5

= 5/5 = 1.

Bài 2:

y x 6/7 = 3/4 + 2

y x 6/7 = 15/4

       y   = 15/4 : 6/7

       y   = 35/8.

K mình nha!

Answer 3

\(\frac{7}{5}-\frac{6}{5}:3\)

\(=\frac{7}{5}-\frac{2}{5}\)

\(=\frac{5}{5}\)

\(=1\)

Answer 4

y x\(\frac{6}{7}=\frac{3}{4}+2\)

y x \(\frac{6}{7}=\frac{11}{4}\)

y \(=\frac{11}{4}:\frac{6}{7}\)

y\(=\frac{77}{24}\)
