( y - \(\dfrac{2}{3}\)) : \(\dfrac{4}{5}\) = \(\dfrac{5}{6}\)
y - \(\dfrac{2}{3}\) = \(\dfrac{5}{6}\) \(\times\) \(\dfrac{4}{5}\)
y - \(\dfrac{2}{3}\) = \(\dfrac{2}{3}\)
y = \(\dfrac{2}{3}\) + \(\dfrac{2}{3}\)
y = \(\dfrac{4}{3}\)
tìm y
y x 2 1/3 = 5/6 + 3,2
2 3/4 - y = 3 2/3 : 1 5/6
Câu 3 Tìm y
a.[y-2\5]/4\3=3\8
5\4-y*5\6=1\4+1\3
tìm y
a ,2/5 + y = 1
b , 6/8 - y= 3/5
c , y / 6 = 7/4
d , y -1/3 = 5 * 2/3
bài 3: Tính
a) \(\dfrac{4}{5}x\dfrac{5}{8}:\dfrac{4}{5}\)
b) \(\dfrac{5}{6}+\left(\dfrac{1}{2}:\dfrac{3}{2}+\dfrac{4}{5}\right)\)
bài 4 Tìm y
\(\dfrac{3}{4}+y:\dfrac{2}{5}=\dfrac{37}{16}\) 456 + y : 87 = 23987
bài 3: Tìm y
a) \(\dfrac{1}{2}\) : y x \(\dfrac{3}{5}=\dfrac{4}{3}+\dfrac{3}{4}\) b) \(\dfrac{4}{3}-\dfrac{1}{2}\) x y \(=1\) c) \(\dfrac{1}{4}+y\) : \(\dfrac{1}{3}=\dfrac{5}{6}\)
1,Tìm y biết
a, 1/3 + 1/6 : (y - 2 và 1/5) = 3/4
b, y * 3,5 -y*1,7=81,846
c,y * 2 và 1/5-y *4/7=5/77
Tìm y
y + y x 1/3 : 2/9 + y : 2/7 = 25
y : 4 + y : 3 + y = 5/6
y x 5 + y x 3 + y + y =50
tìm y biết : 9/4 - y x 5/6 = 1/2 + 2/3
tìm y biết 7/4-y * 5/6 = 1/2+1/3.vậy y =
