= \(\dfrac{2021x2022+2021-1}{2021x2022+2020}\)
= \(\dfrac{2021x2022+2020}{2021x2022+2020}\)
= 1
= \(\dfrac{2021x2022+2021-1}{2021x2022+2020}\)
= \(\dfrac{2021x2022+2020}{2021x2022+2020}\)
= 1

Tính nhanh phân số
A = \(\dfrac{2018\times2020+2020\times2022}{2020\times4040}\)
B = \(\dfrac{111\times118-33}{112\times115+185}\)
Ai nhanh mình tick cho
a 6 x 8 x 5 b/ 12 x 13 x 14 c/ 2323 x 123123

Tính nhanh phân số
a) Tính bằng cách thuận tiện
12/15 + 4/3 + 1/4 + 3/4 + 5/3 + 3/15
b) Tìm X
X x 3/4 = 1/6 x 3/5 x 6/5 x 5/3 (MÌNH CẦN GẤP ĐỂ NỘP)
rút gọn phân số: \(\dfrac{78}{45}\)
tính: \(\dfrac{13}{17}\) + \(\dfrac{31}{34}\) =
a, 6/7 - 4/21
b, 6 x 12/18
c, 2/5 x 3/7 + 2/5 x 4/7
giúp tui nhe
x:5/11=22 tìm x
5/4 x X = 3/8
23/69 - x = 17/153
1/5 : 4/7 : x = 3/5
