a: Tổng số phần sách các tổ I,II,III đã góp là:

\(\dfrac{1}{3}+\dfrac{1}{12}+\dfrac{7}{16}=\dfrac{41}{48}\)(phần)

b: Tổ IB đã góp: \(1-\dfrac{41}{48}=\dfrac{7}{48}\left(phần\right)\)

c: \(\dfrac{1}{3}=\dfrac{1\cdot16}{3\cdot16}=\dfrac{16}{48};\dfrac{1}{12}=\dfrac{1\cdot4}{12\cdot4}=\dfrac{4}{48};\dfrac{7}{16}=\dfrac{7\cdot3}{16\cdot3}=\dfrac{21}{48};\dfrac{7}{48}=\dfrac{7}{48}\)

mà 4<7<16<21

nên \(\dfrac{1}{12}< \dfrac{7}{48}< \dfrac{1}{3}< \dfrac{7}{16}\)

=>Tổ III góp nhiều nhất

a/Tổng số phần sách của lớp các tổ I, tổ II và tổ III đã góp:
\(\dfrac{1}{3}+\dfrac{1}{12}+\dfrac{7}{16}=\dfrac{41}{48}\)(số sách)
b/Số phần sách của lớp tổ IV đã góp:
\(1-\dfrac{41}{48}=\dfrac{7}{48}\)(số sách)
c/Ta có:
\(\dfrac{1}{3}=\dfrac{16}{48}\)
\(\dfrac{1}{12}=\dfrac{4}{48}\)
\(\dfrac{7}{16}=\dfrac{21}{48}\)
\(\dfrac{7}{48}=\dfrac{7}{48}\)
Do \(\dfrac{4}{48}< \dfrac{7}{48}< \dfrac{16}{48}< \dfrac{21}{48}\) nên trong lớp 6A, tổ III góp nhiều sách nhất

\(\dfrac{24}{17}\left(-0,875+45\%\right)-2\dfrac{1}{5}\)

\(=\dfrac{24}{17}\left(-\dfrac{7}{8}+\dfrac{9}{20}\right)-2,2\)

\(=\dfrac{24}{17}\cdot\dfrac{-7\cdot5+9\cdot2}{40}-2,2\)

\(=\dfrac{24}{40}\cdot\dfrac{-35+18}{17}-2,2\)

\(=-0,6-2,2=-2,8\)

Nếu k là số lẻ thì 15k + 1 là số chẵn hay 15k + 1 là hợp số.

Nếu k là số chẵn thì 15k + 1 có thể là hợp số cũng có thể là số nguyên tố.

Với mọi k \(\in\) N thì 15k + 1 là hợp số hay nguyên tố chưa thể xác định được.

phần a sai đề bạn nhé
