\(\frac{28}{3}\)

giải cách làm hộ mình nhé

\(\subset\frac{161616}{212121}+\frac{12036}{21063}\supset\times7\)

\(\subset\frac{161616:10101}{212121:10101}+\frac{12036:1003}{21063:1003}\supset\times7\)

\(\subset\frac{16}{21}+\frac{12}{21}\supset\times7\)

\(\frac{28}{21}\times7\)

\(\frac{196}{21}\)

\(\frac{28}{3}\)

tick đó nha

=(16/12+4/7)*7

=40/21*7

=40/3

=10 nha Thu Hiền

(161616/212121+2022/3033)*7

=10

mk nhanh nhất nha

Đ/s: 10 nhé bạn.

​​​​(161616\212121+2022\3033)*7

=(\(\frac{161616}{212121}+\frac{2022}{3033}\))*7

=(\(\frac{16}{21}+\frac{2}{3}\)​​)*7

=\(\frac{30}{21}\)*7

=\(\frac{210}{21}\)

=10

bằng 10, đúng 100%

\(\left(\frac{161616}{212121}+\frac{2022}{3033}\right)\times7=\left(\frac{16.10101}{21.10101}+\frac{1011.2}{1011.3}\right)\times7=\left(\frac{16}{21}+\frac{2}{3}\right)\times7\)

\(=\frac{10}{7}\times7=10\)

Bài làm

\(\left(\frac{161616}{212121}+\frac{2022}{3033}\right)x7\)

= \(\left(\frac{16}{21}+\frac{2}{3}\right)x7\)

= \(\left(\frac{16}{21}+\frac{14}{21}\right)x7\)

= \(\frac{30}{21}x7\)

= \(\frac{30}{3}\)

= \(10\)

# Chúc bạn học tốt #

=15/16+16/24

15/21+16/24

=\(\frac{15}{21}x\frac{16}{24}\)

=\(\frac{5}{7}x\frac{2}{3}\)

=\(\frac{10}{21}\)

ko nhanh đc đâu

mình xin chịu bài này

cho miik hỏi nha nếu bạn có cồng viết mà vôị thì bạn có thể viết lên gg mà:)

a)\(\frac{1}{2}:\frac{1}{5}+\frac{1}{3}:\frac{1}{5}+\frac{1}{6}:\frac{1}{5}\)

=\(\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{6}\right):\frac{1}{5}\)

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

=5

b)\(\frac{1515\text{×}161616}{151515\text{×}1616}\)

=1
