GIÚP MÌNH Ạ
x: 4,37= 5,6 { dư 1,53}
x = 5,6. 4,37 + 1,53
x= 26,002
Tìm y biết
a , y: 4,37=5,6 (dư 1,53)
b, 13,5 x ( y:5,6 )= 36,45
Tìm x :
x : 4,37 = 5.6 ( dư 1,53 )
giúp mình nha tại lười
x : 4,37 = 5,6 ( dư 1,53 )
x = 5,6 x 4,37 + 1,53
x = 24,472 + 1,53
x = 26,002
x : 4,37 = 5,6 ( dư 1,53 )
x = 5,6 . 4,37 + 1,53
x = 26,002
x : 4,37 = 5,6 ( dư 1,53 )
x = 5,6 x 4,37 + 1,53
x = 24,472 + 1,53
x = 26,002
Chúc học tốt nhé!!!

\(1,\)
\(a,1+\frac{1}{3}+\frac{1}{9}+\frac{1}{27}+\frac{1}{81}\)
\(=\frac{81}{81}+\frac{27}{81}+\frac{9}{81}+\frac{3}{81}+\frac{1}{81}\)
\(=\frac{81+27+9+3+1}{81}\)

giup mik nha !!!
1. Tính bằng cách thuận tiện nhất :
a, 0,125 x 6,135 x 24 =.............................
= ............................
b, 5m2 7dm2 + 2,6m2 + 3,33m2 =.......................
= ........................
2. Tìm x :
a, x : 4,37 = 5,6 ( dư 1,53 ) b, 13,5 x ( x : 5,6 ) = 36,45
Giúp mk với ai nhanh 3 tick nha !!!!!!!!!!
a) 0,125 x 6,135 x 24 = 0,125 x 24 x 6,135
= 3 x 6,135
= 18,405
b, 5 m2 7 dm2 + 2,6 m2 + 3,33 m2 = 5,07 m2 + 2,6 m2 + 3,33 m2
= (5,07 m2 + 3,33 m2) + 2,6 m2
= 8,4 m2 + 2,6 m2
= 11 m2

6,25 x X+X x 3,75 = 49,36
Lời giải:
$6,25\times x+x+x\times 3,75=49,36$
$x\times (6,25+1+3,75)=49,36$
$x\times 11=49,36$
$x=49,36:11=4,49$
