Tính nhanh:
A = \(\frac{\frac{2}{13}+\frac{2}{15}-\frac{2}{11}}{\frac{68}{34}+\frac{68}{30}-\frac{68}{22}}+\frac{\frac{32}{10}+\frac{32}{14}-\frac{32}{18}}{\frac{17}{5}+\frac{17}{7}-\frac{17}{9}}\)
\(\frac{34}{11}\)x\(\frac{1269}{46}\)x\(\frac{23}{17}\)x\(\frac{22}{9}\)
\(\frac{11}{17}\) : \(\frac{33}{34}\) = ?
1. Tính :
\(\frac{21}{11}x\frac{22}{17}:\frac{42}{34}\)Mọi người giúp em với ạ ! ai nhanh em cho 3 tick nhé
\(\frac{1}{7}+\frac{1}{8}+\frac{1}{9}+\frac{1}{10}+\frac{1}{11}+\frac{1}{12}+\frac{1}{14}+\frac{1}{15}+\frac{1}{18}+\frac{1}{22}+\frac{1}{24}+\frac{1}{28}+\frac{1}{33}\)
7/9 * 3/35 =
9/22 * 55 =
11/17: 33/34
* là nhân nhé các bạn
7/9 x 3/5 = ?
9/22 x 55 = ?
11/17 : 33/34 = ?
Tính :
a)\(\frac{9}{22}x\frac{33}{18}\)
b)\(\frac{12}{35}:\frac{36}{25}\)
c)\(\frac{19}{17}:\frac{76}{51}\)
Giúp mình với !
Trả lời được tích !
