=11 x (35 + 42 + 22 + 1)

=11 x 100

=1100

học tốt em nhé

  35 x 11+42x11+22x11+11
= (35 + 42 + 22 +11 ) x11 =
= 110 x11 
=1210

bằng = 4,950

\(=\dfrac{11}{12}\left(\dfrac{2}{7}+\dfrac{4}{7}+\dfrac{1}{7}\right)=\dfrac{11}{12}\cdot1=\dfrac{11}{12}\)

=11/12

11/12 nha

7/11+3/4+4/11+1/4=(7/11+4/11)+(3/4+1/4)=1+1=2 nha

7/11+3/4+4/11+1/4= (7/11+4/11)+(3/4+1/4)

                            =11/11+4/4=1+1=2

Chúc bạn học tốt!

( 7/11 + 4/11 ) + ( 3/1 + 1/4 ) 

= 1 + 1

= 2

chúc bạn hoc tốt nhé

\(\frac{5}{11}.\frac{7}{25}+\frac{15}{11}.\frac{1}{5}\)

\(=\frac{5}{11}.\frac{7}{25}+\frac{5}{11}.3.\frac{1}{5}\)

\(=\frac{5}{11}.\frac{7}{25}+\frac{5}{11}.\frac{3}{5}\)

\(=\frac{5}{11}\left(\frac{7}{25}+\frac{3}{5}\right)\)

\(=\frac{5}{11}\left(\frac{7}{25}+\frac{15}{25}\right)\)

\(=\frac{5}{11}.\frac{22}{25}=\frac{2}{5}\)

2/5 nhé

   5/11x7/25+15/11x1/5

=5/11x(7/25+1/5)

=5/11x12/25

=12/55

Chúc bn hok tốt
