`4/5-y=1/3:2`
`4/5-y=1/6`
`y=4/5-1/6`
`y=19/30`
Vậy `y=19/30`
`@An`
4/5 - y = 1/3 : 2
4/5 - y = 1/3 x 1/2
4/5 - y = 1/6
y = 4/5 -1/6
y = 19/30
bài 1: Tính
a} 5/12 + 1/3 x 3/5 =
B 7/5 - 4/9 : 2/5 =
C 2/5 x 1/4 : 2/5 =
bài 2: Tìm y
a 42/25 : y/5 = 5/6
b 27/y : 9/4 = 3/7
1.tìm y.giải ra
a) y + 3/7 x 21/9 = 5
b) y x 3/5 - 1/2 = 4/5
c)9/8 - y + 2/5 = 1/4
d) y - 6/5 : 2/3 = 5/6
e) y : 7/8 + 3/4 = 7/4
giúp mk,mai đi hok thêm mk nộp!!!
1.Tìm y, biết: a) y × 2/5 + y × 3/5 = 5/7 b) y × 7/2 - y × 3/2 = 3/4
tìm y
3/5 x y + 1/2 : 5/3 - 5/4 = 1/2 x 1/3
tìm y;
Y x 3/1/3=3/1/3 : 4/1/4
hỗn số đó
5/2/3: Y =3/2/3-2/1/2
tìm y biết 2/3 x 4/y x 1/5=4/45
3/4 x y/5=5/2 x 9/10
Tìm y
a) y x 6/7 = 5/14
b) y : 2/3 = 4/9
c) 3/10 + y = 1/2
d) 5/6 - y = 1/3
1 , 3/4 x 8 - y = 1 2/5
2, 3/4 : 2/4 + y = 19/15
Tìm Y
Y : 1/5 = 7
5/4 - Y=2/3
5/12 + 1/3 =
1 - 3/4 =
2 × 3/11 =
8/7 :4 =
Tìm y
2/5 : y = 1/3 y : 7/11 = 22
