Mình ko hiểu

Bạn viết lại đề bài đi rồi mình giải cho

75phan100 + 3phan4 x29 +76% x 30 + 0,75 x40

\(\frac{75}{100}+\frac{3}{4}.29+75\%.30+0,75.40\)

\(=\frac{75}{100}+\frac{3}{4}.29+\frac{75}{100}.30+\frac{75}{100}.40\)

\(=\frac{3}{4}+\frac{3}{4}.29+\frac{3}{4}.30+\frac{3}{4}.40\)

\(=\frac{3}{4}.\left(1+29+30+40\right)\)

\(=\frac{3}{4}.100\)

\(=75\)
