\(\frac{-7}{25}.\frac{11}{13}+\frac{-7}{25}.\frac{2}{13}-\frac{18}{25}\)
= \(\frac{-7}{25}.\left(\frac{11}{13}+\frac{2}{13}\right)-\frac{18}{25}\)
= \(\frac{-7}{25}-\frac{18}{25}\)
= - 1
Ai giúp mk bài này với:
-7/25.11/13+-7/25.2/13-18/25
-7/25 × 11/13 + -7/25 × 2/13 - 18/25
-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
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+2/13-18/25
Tính hợp lí.😆😆😆
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
A -17/30 + 11/15 - 7/12
1/2+3/4-(3/4-4/5)
-7/25×11/13+ -7/25×2/13-18/25
(-3,2)+ -15/64+(0,8-2 4/15)÷3 2/3
-5/9+5/9÷(1 2/3- 2 1/12)
-5/7×2/11+ -5/7×9/11+ 1 5/7
(3/8+ -3/4+7/12)÷5/6+1/2
50%×1 1/3×10×7/35×0,75
