Tìm x
\(\dfrac{25-x}{56}\) = \(\dfrac{6}{16}\)
`(25-x)/56 = 6/16`
`=> (25-x)xx16= 56xx6`
`=> (25-x)xx16= 336`
`=> 25-x=336:16`
`=> 25-x=21`
`=>x=25-21`
`=>x=4`
`(25 - x)/56 = 6/16`
`=> (25 - x)/56 = 3/8`
`=> (25 - x)/56 = 21/56`
`=> 25 -x = 21`
`=> x = 25 - 21`
`=> x = 4`
Vậy `x = 4`
25-x/56=6/16
\(25-\frac{x}{56}=\frac{6}{16}\)
\(\frac{x}{56}=25-\frac{6}{16}\)
\(\frac{x}{56}=24,625\)
\(x=24,625\times56\)
\(x=1379\)
25-x/56=6/16
x/56=25-6/16
x/56=24.526
x=24.625x56
x=1379
vay =1379
25-x/56=6/16
25-x/56=6/16
x/56=25-6/16
x/56=24\(\frac{5}{8}\)
x/56=24\(\frac{35}{56}\)
x/56=\(\frac{24\times56+35}{56}\)
x/56=\(\frac{1379}{56}\)
Vậy số cần tìm là:\(\frac{1379}{56}\)
25-\(\frac{x}{56}=\frac{6}{16}\)
\(\frac{x}{56}=25-\frac{6}{16}\)
\(\frac{x}{56}=\frac{197}{8}\)
\(\frac{x}{56}=\frac{1379}{56}\)
=>x=1379
Tìm x:
25 - x/56 = 6/16
\(x=\left(25-\dfrac{6}{16}\right).56=1379\)
25-x/56=6/16
tìm x
Ta có :25-x/56=6/16 <=>25-x/56=3/8
Gọi 25-x là y =>y/56=3/8
=>y=56 nhân 3 chia 8 vậy y =21
tương đương 25-x=21
x=25-21=4
Vậy x=4 thì 25-x/56=6/16

Vào trang này đi. kết quả đó
25 - x : 56 = 6 : 16
x : 56 = 6/16 + 25
x : 56 = 25 , 375
x= 25,375 x 56
x=1421 .
\(\frac{25-x}{56}=\frac{6}{16}\)
Tìm x
\(\frac{25-x}{56}=\frac{6}{16}\)
\(\frac{25-x}{56}=\frac{3}{8}\)
\(\frac{25-x}{56}=\frac{21}{56}\)
\(\Rightarrow25-x=21\)
\(\Rightarrow x=25-21\)
\(\Rightarrow x=4\)
Vậy x=4
=>(25-x)16=6x56=280
25-x=17.5
x=7.5=15/2
vậy x=15/2
ta giản ước : 6/16 = 3/8 như vậy, ta có :
\(\frac{25-x}{56}=\frac{3}{8}\)
quy đồng 2 phân số cho nhau : ( mẫu số chung ) = 56
ta có : 56 : 8 = 7
\(\frac{3x7}{8x7}=\frac{21}{56}\)
bây giờ, bài toán sẽ như sau :
\(\frac{25-x}{56}=\frac{21}{56}\)
vậy, x = 25 - 21 = 4
k mk nha
chúc bạn học giỏi
tim x
\(\frac{25-x}{56}=\frac{6}{16}\)
25 - x / 56 = 6/16
( 25 - x ) : 56 = 6/16
25 - x = 6/16 x 56
25 - x = 21
x = 25 - 21
x = 4
\(\frac{25-x}{56}=\frac{6}{16}\)
\(\frac{x}{56}=25-\frac{6}{16}\)
\(\frac{x}{56}=24\frac{5}{8}\)
\(\frac{x}{56}=24\frac{35}{56}\)
\(\frac{x}{56}=\frac{24\cdot56+35}{56}\)
\(\frac{x}{56}=\frac{1379}{56}\)
Vậy số cần tìm là \(1379\)
25-X= 6x56:16
25-X=21
X=25-21
X=4
K cho mình nhé, ai có facebook thì kb với mình luôn nha <3
tim x biet : \(\frac{25-x}{56}=\frac{6}{16}\)
25-x/56 = 6/16
=> 2.(25-x)/112=7.6/112
=> 2.(25-x)= 42
=> 50 - 2x = 42
=> -2x = 50 - 42
=> -2x = 8
=> x = 8:(-2)
=> x = 4
Tìm x: \(\frac{25-x}{56}=\frac{6}{16}\)
Theo đề ta có: \(\frac{25-x}{56}=\frac{6}{16}\)
Ta rút gọn: \(\frac{25-x}{56}=\frac{3}{8}\)
\(\Leftrightarrow\)25 -x . 8 = 56 . 3
\(\Rightarrow\)25 - x . 8 = 168
\(\Rightarrow\)25 - x = 168 : 8
\(\Rightarrow\)25 - x = 21
\(\Rightarrow\) - x = 21 - 25
\(\Rightarrow\) - x = -4
\(\Rightarrow\) x = 4
Vậy x = 4.
Tìm x biết:
\(\frac{25-x}{56}\)=\(\frac{6}{16}\)
\(\frac{25-x}{56}=\frac{6}{16}\)
\(\Rightarrow\frac{25-x}{56}=\frac{3}{8}\)
\(\Rightarrow\left(25-x\right).8=56.3\)
\(\Rightarrow25.8-8x=168\)
\(\Rightarrow200-8x=168\)
\(\Rightarrow8x=200-168\)
\(\Rightarrow8x=32\)
\(\Rightarrow x=32:8\)
\(\Rightarrow x=4\)
Tham khảo nha !!!
Cách này dễ hơn nèk :
\(\frac{25-x}{56}=\frac{6}{16}\)
\(\Leftrightarrow\)\(\frac{25-x}{56}=\frac{3}{8}\)
\(\Leftrightarrow\)\(\frac{25-x}{56}=\frac{21}{56}\)
\(\Leftrightarrow\)\(25-x=21\)
\(\Leftrightarrow\)\(x=25-21\)
\(\Leftrightarrow\)\(x=4\)
Vậy \(x=4\)
Chúc bạn học tốt ~
Nhân chéo là ra mà
56 x 6 = 25 - X x16
=56 x 6 : 16 = 21
25 - 21 = 4
Vậy X bằng 4
