Question

7.tính bằng cách thuân tiện

1/11+3/4+4/11+1/4

Answer 1

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

=5/11 + 4/4

=5/11+1

=5/11+ 11/11

=16/11

Answer 2

\(\frac{1}{11}+\frac{3}{4}+\frac{4}{11}+\frac{1}{4}\)

\(=\left(\frac{1}{11}+\frac{4}{11}\right)+\left(\frac{3}{4}+\frac{1}{4}\right)\)

\(=\frac{5}{11}+1\)

\(=1\frac{5}{11}\)

Answer 3

1/11+3/4+4/11+1/4

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

=5/11+1

=16/11

Answer 4

\(\frac{1}{11}+\frac{3}{4}+\frac{4}{11}+\frac{1}{4}\)

= \(\left(\frac{1}{11}+\frac{4}{11}\right)+\left(\frac{3}{4}+\frac{1}{4}\right)\)

= \(\frac{5}{11}+1\)

= \(\frac{16}{11}\)

k mình nhé mình trả lời nhanh nhất , đúng nhất và đầy đủ nhất

Answer 5

= ( \(\frac{1}{11}\)+   \(\frac{4}{11}\))  + \(\frac{3}{4}\)+   \(\frac{1}{4}\)

= \(\frac{5}{11}\)+  ( \(\frac{3}{4}\)+   \(\frac{1}{4}\))  

=   \(\frac{5}{11}\)+  \(\frac{5}{4}\)

=  \(\frac{75}{44}\)

Answer 6

1/11 + 3/4 + 4/11 + 1/4

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

= 5/11 + 1 

= 16/11

Answer 7

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

=5/11+1

=5/11+11/11

=16/11

Chúc bạn học giỏi 

k nhé♡♡♡

Answer 8

sorry bn mk làm nhầm ! kết quả là \(\frac{16}{11}\)

Answer 9

\(\frac{1}{11}\)\(+\)\(\frac{3}{4}\)\(+\)\(\frac{4}{11}\)\(\frac{1}{4}\)

\(=\)(\(\frac{1}{11}\)\(+\)\(\frac{21}{11}\))\(+\)(\(\frac{3}{4}\)\(+\)\(\frac{1}{4}\))

\(=\)\(\frac{5}{11}\)\(+\)\(1\)

\(=\)\(\frac{16}{11}\)
