14/27:7/18*6/5+3/10
14/27 : 7/18 × 6/5 + 3/10
\(\frac{14}{27}:\frac{7}{18}\cdot\frac{6}{5}+\frac{3}{10}\)
\(=\frac{14}{27}\cdot\frac{18}{7}\cdot\frac{6}{5}+\frac{3}{10}\)
\(=\frac{14\cdot18\cdot6}{27\cdot7\cdot5}+\frac{3}{10}\)
\(=\frac{2\cdot7\cdot9\cdot2\cdot3\cdot2}{3\cdot9\cdot7\cdot5}+\frac{3}{10}\)
\(=\frac{8}{5}+\frac{3}{10}\)
\(=\frac{16}{10}+\frac{3}{10}\)
\(=\frac{19}{10}\)
14/27 ÷ 7/18 × 6/5 + 3/10 =
\(\frac{14}{27}:\frac{7}{18}\cdot\frac{6}{5}+\frac{3}{10}\)
\(=\frac{4}{3}\cdot\frac{6}{5}+\frac{3}{10}\)
\(=\frac{8}{5}+\frac{3}{10}\)
\(=\frac{19}{10}\)
. là nhân nha
tính
14/27 : 7/18 * 6/5 + 3/10
bằng 19/10 nha bạn
chú ý:
/ là phân số
14/27 : 7/18 x 6/5 + 3/10
giúp mik câu này nữa nha
= 4/3 x 6/5 + 3/10
= 8/5 +3/10
= 19/10
a) 2^7 . 9^3 / 6^5 . 8^2
b) 6^10 . 27^5 / 4^5 . 81^6
c) 3^18 . 32^9 / 64^7 . 27^6
d) 9^12 . 3^5 + 9^15 / ( 2. 27 )^5 . 3^14
e) 5^4 + 2^2 . 5^2 - 125 / 2^3 . 3
a) 2^7 . 9^3 / 6^5 . 8^2
= 2^7 . 3^9 / 2^5 . 3^5 . 2^6
= 2^-4 . 3^4
thực hiện phép tính
E = (12/35-6/ 7+18/14):6/-7-(-2/5)-1
G=(-5/7-7/9+9/11-11/13)(12/4-3/4)/ (10/21+14/27-6/11+22/39):(6/3-2/3)
nếu làm nhanh ngay thì tick và followwwww
B = -3 - 2/3 + 3/5 (-10/9 - 25/3) - 5/6
C = (12/35 - 6/7 + 18/14 : 6/-7 - -2/5-1
D = [(-54/64 - (1/9 : 8/27 :-81/128]
thực hiện phép tính
1/2+3/5+2/6
7/5+1/7+14/10+1
3/7+1/5+1/7+2/10+2
15/27+1/9+3/5+2/18
\(\frac{1}{2}+\frac{3}{5}+\frac{2}{6}=\frac{11}{10}+\frac{2}{6}=\frac{43}{30}\)
\(\frac{7}{5}+\frac{1}{7}+\frac{14}{10}+1=\frac{54}{35}+\frac{14}{10}+1=\frac{129}{35}\)
