Question

5/5 + 9/9 + 16/7 + 1 =

1/5 + 2/9 + 4/5 +16/7

nhanh lên các bạn ơi. mình cảm ơn trước

 

 

Answer 1

\(\frac{5}{5}+\frac{9}{9}+\frac{16}{7}+1\)

\(=\left(\frac{5}{5}+\frac{9}{9}+1\right)+\frac{16}{7}\)

\(=\left(1+1+1\right)+\frac{16}{7}\)

\(=3+\frac{16}{7}\)

\(=\frac{37}{7}\)

\(\frac{1}{5}+\frac{2}{9}+\frac{4}{5}+\frac{16}{7}\)

\(=\left(\frac{1}{5}+\frac{4}{5}\right)+\left(\frac{2}{9}+\frac{16}{7}\right)\)

\(=1+\frac{158}{63}\)

\(=\frac{221}{63}\)

Answer 2

5/5 + 9/9 + 16/7 + 1 = 37/7

1/5 + 2/9 + 4/5 +16/7= 221/63

Answer 3

5/5+9/9+16/7+1=1+1+16/7+1=2+23/7=37/7

1/5+2/9+4/5+16/7=(1/5+4/5)+2/9+16/7=1+2/9+16/7=11/9+16/7=221/63

Mình nghĩ thế. Nếu sai cho mình xin lỗi.

Answer 4

5/5+9/9+16/7+1

=1+1+1+14/7+2/7

=3+2+2/7

=5+2/7

Answer 5

5/5 + 9/9 + 16/7 + 1 = 1 + 1 + 16/7 + 1

                                = 3 + 16/7

                                = 21/7 + 16/7

                                = 27/7

1/5 + 2/9 + 4/5 + 16/7 = (1/5 + 4/5) + (2/9 + 16/7)

                                   = 5/5 + 158/63

                                   = 63/63 + 158/63

                                   = 221/63

Chúc bạn hok tốt nha!

Answer 6

5/5 + 9/9 + 16/7 + 1 = 1 + 1 + 16/7 + 1

                                = 3 + 16/7

                                = 37/7

1/5 + 2/9 + 4/5 + 16/7 = ( 1/5 + 4/5 ) + 2/9 + 16/7

                                   =           1        + 188/63

                                   =                   188/63

Answer 7

1/ 5/5 + 9/9 + 16/7 +1 

= ( 5/5 + 9/9 ) + ( 16/7 +1 )

= 2 + 23/7

= 37/7

2/ 1/5 + 2/9 + 4/5 + 16/7

= ( 1/5 + 2/9) + ( 4/5 + 16/7 )

= 19/45 + 108/35

= 221/63
