Question

7/9 + 2/3 + 2/9 + 1= ......,..........

Mọi người ơi giải giúp mình nhé cần gấp😍

Answer 1

= 7/9 + 6/9 + 2/9 + 9/9

= 13/9 + 2/9 + 9/9

= 15/9 + 9/9

= 24/9

= 8/3

Answer 2

\(\frac{7}{9}+\frac{2}{3}+\frac{2}{9}+1\)

\(=\left(\frac{7}{9}+\frac{2}{9}\right)+1+\frac{2}{3}.\)

\(=1+1+\frac{2}{3}.\)

\(=2\frac{2}{3}.\)

Answer 3

(7/9+2/9)+2/3+1

1+2/3+1

1/1+2/3+1/1

3/3+2/3+3/3

5/3+3/3

8/3

Answer 4

\(\frac{7}{9}+\frac{2}{3}+\frac{2}{9}+1\)

\(=(\frac{7}{9}+\frac{2}{9})+\frac{2}{3}+1\)

\(=1+1+\frac{2}{3}\)

\(=2+\frac{2}{3}\)

\(=\frac{6}{3}+\frac{2}{3}=\frac{8}{3}\)

Chúc bạn học tốt

Answer 5

\(\frac{7}{9}\)+\(\frac{2}{3}\)+\(\frac{2}{9}\)+1

=\(\frac{1}{1}\)+\(\frac{2}{3}\)+\(\frac{1}{1}\)

= \(\frac{8}{3}\)

dễ quá !!!:))

Answer 7

dễ quá !!!:))

Answer 8

Bài làm:

\(\frac{7}{9}+\frac{2}{3}+\frac{2}{9}+1\)

\(=\frac{7}{9}+\frac{6}{9}+\frac{2}{9}+\frac{9}{9}\)

\(=\frac{24}{9}\)

\(=\frac{8}{3}\)

Answer 9

7/9+2/3+2/9+1

=7/9+6/9+2/9+1

=15/9+1=24/9

=8/3

Answer 10

7/9 + 2/3 + 2/9 + 1
