\(=\dfrac{-7}{25}\left(\dfrac{11}{13}+\dfrac{2}{13}\right)-\dfrac{18}{25}=-1\)
\(=\dfrac{-7}{25}\left(\dfrac{11}{13}+\dfrac{2}{13}\right)-\dfrac{18}{25}=-1\)
-7/25 × 11/13 + -7/25 × 2/13 - 18/25
thực hiện phép tính :
a, -7/25 . 11/13 + -7/25 . 2/13 - 18/25
-7/25×11/13+(-7)/25+2/13-18/25
Tính hợp lí.😆😆😆
Bài 1 : Thực hiện phép tính sauuu
a) -17/30 - 11/-15 + -7/12
b) -5/9 + 5/9 : ( 5/3 - 25/12)
c) -7/25 . 11/13 + -7/25 . 2/13 - 18/25
-7/25. 11/13 + -7/25.2/3 -18/25
Bài 1: Thực hiện phép tính:
1) \(\dfrac{-17}{30}-\dfrac{11}{-15}+\dfrac{-7}{12}\)
2) \(\dfrac{-5}{9}+\dfrac{5}{9}:\left(1\dfrac{2}{3}-2\dfrac{1}{12}\right)\)
3) \(\dfrac{-7}{25}.\dfrac{11}{13}+\dfrac{-7}{25}.\dfrac{2}{13}-\dfrac{18}{25}\)
a) -7/25 . 11/13 + -7/25 . 2/13 - 18/25
b) 5/7 . 1/3 - 5/7 . 1/4 - 5/7 . 1/12
c) 5 + 2/5 . 4+ 2/7 + 5 + 5/7 . 5+ 2/5
d) 75% - 3/2 + 0,5 - [ -1/2]^2
1Tính
-4/25 × 11/13 + -2/25 × 7/15 - 18/25
2Tim x
45% của x bằng 3/10
a )-\(-\frac{17}{30}-\frac{11}{-15}+-\frac{7}{12}\)
b ) \(-\frac{5}{9}+\frac{5}{9}:\left(1\frac{2}{3}-2\frac{1}{12}\right)\)
c ) \(-\frac{7}{25}.\frac{11}{13}+-\frac{7}{25}.\frac{2}{13}-\frac{18}{25}\)
