\(\frac{3636}{3535}+\frac{5454}{4242}\)
\(=\frac{36}{35}+\frac{54}{42}\)
= \(\frac{36}{35}+\frac{9}{7}\)
= \(\frac{36}{35}+\frac{45}{35}\)
= \(\frac{81}{35}\)
\(\frac{3636}{3535}+\frac{5454}{4242}\)
\(=\frac{36}{35}+\frac{54}{42}\)
= \(\frac{36}{35}+\frac{9}{7}\)
= \(\frac{36}{35}+\frac{45}{35}\)
= \(\frac{81}{35}\)
\(C=\frac{3535\cdot232323}{353535\cdot2323}\)VÀ \(D=\frac{3535}{3534}\)
\(\frac{121212+12121212-1212}{363636+36363636-3636}\)
Nhờ các bạn tính nhanh hộ mình
tính nhanh:
\(\frac{1212}{1515}+\frac{1212}{3535}+\frac{1212}{6363}+\frac{1212}{9999}\)
M = \(\frac{7}{4}x\left(\frac{3333}{1212}+\frac{3333}{2020}+\frac{3333}{3030}+\frac{3333}{4242}+\frac{3333}{5656}\right)\)
Tính A= \(\frac{7}{4}\)x (\(\frac{3333}{1212}+\frac{3333}{2020}+\frac{3333}{4242}+\frac{3333}{3030}\))
điền dấu < > = thích hợp vào chỗ ......
\(\frac{3535}{7272}\)+ \(\frac{111111}{242424}\)......... 1
chỉ cần đáp án ai nhanh mình tick nhé
\(\frac{505}{1212}\) +\(\frac{505}{2020}\)+\(\frac{505}{3030}\)+\(\frac{505}{4242}\)+\(\frac{505}{5656}\)
tính nhanh :\(\frac{5454}{5757}-\frac{171717}{191919}\)=
1.Tính tổng sau:
\(\frac{1919}{3535}\)+ \(\frac{54545454}{75757575}\)
