Tính giá trị biểu thức
\(\frac{1}{10}+\frac{2}{20}+\frac{9}{30}+\frac{16}{40}+\frac{25}{50}+\frac{36}{60}+\frac{49}{70}+\frac{69}{80}+\frac{81}{90}\)
1 .rút gọn rồi quy đồng
a , \(\frac{15}{90}\) ; \(\frac{120}{600}\) ;\(\frac{75}{150}\)
b, \(\frac{54}{90}\) ; \(\frac{180}{288}\) ; \(\frac{60}{135}\)
2 .quy đồng mẫu cac s phân số
a,\(\frac{24}{146}\)và\(\frac{6}{13}\)
b, \(\frac{7}{30}\) ;\(\frac{13}{60}\) ; \(\frac{9}{40}\)
c , \(\frac{17}{60}\) ; \(\frac{5}{18}\) ; \(\frac{64}{90}\)
d, \(\frac{4}{7}\) ; \(\frac{8}{9}\) ; \(\frac{10}{21}\)
để \(\frac{a}{90}\)= \(\frac{24}{60}\)thì a = bao nhiêu
ai làm đúng mình tick cho
\(60+90\times\frac{3}{5}\)
kb với mk nha
Tìm số tự nhiên n sao cho :
\(\frac{54}{11}\cdot\frac{121}{27}< n< \frac{100}{21}:\frac{25}{126}\)
\(\frac{x}{4}\)< \(\frac{126}{72}\)
\(\frac{x}{4}\)< \(\frac{126}{72}\)
\(\frac{189}{209}\) x \(\frac{1291}{3290}\)= ?
