46: 24 + 8: 24 = (46 +8): 24 = 54 : 24 = 2,25.

Câu 1:

a)46:24+8:24=(46+8):24=\(\frac{54}{24}\)

b)1,25:4,9x0,9=\(\frac{45}{196}\)

tinh nhanh nha

46:24+8:24

=(46+8):24

=54:24

=2.25

705:45-336:45

=(705-336):45

=369:45

=8.2

a)   \(46:24+8:24\)                  

\(=\left(46+8\right):24\)

\(=54:24\)

\(=2,25\)

b)  \(705:45-336:45\)

\(=\left(705-336\right):45\)

\(=369:45\)

\(=8,2\)

2,5 / 5,6*1,4

46 : 24 + 8 : 24

= (46 + 8) : 24

= 54 : 24

= 9/4 = 2,25

\(46:24+8:24\)

\(=\left(46+8\right):24\)

\(=54:24\)

\(=\dfrac{54}{24}=\dfrac{9}{4}\)

\(=2,25\)

\(=>\dfrac{43}{8}+x=-\dfrac{46}{3}+\dfrac{173}{24}=-\dfrac{65}{8}\)

\(=>x=-\dfrac{65}{8}-\dfrac{43}{8}=-\dfrac{27}{2}\)

x=-46/3 +173/24 -43/8

x= 368/24 + 173/24 -129/24

x=103/6

a) 2,25

b) 8,2

c) 2,345

d) 6,25

\(\Rightarrow\dfrac{2}{3}=\dfrac{1}{3}.x\)

\(\Rightarrow x=\dfrac{2}{3}:\dfrac{1}{3}\)

\(\Rightarrow x=2\)

\(\dfrac{8}{23}.\dfrac{46}{24}=\dfrac{1}{3}x\\ \Rightarrow\dfrac{1}{3}x=\dfrac{2}{3}\\ \Rightarrow x=\dfrac{2}{3}:\dfrac{1}{3}\\ \Rightarrow x=2\)

a) 52 439 ; 52 440 ; 52 441 ; 52 442 ; 52 443 ; 52 444 ; 52 445.

b) 46 754 ; 46 755 ; 46 756 ; 46 757 ; 46 758 ; 46 759 ; 46 760.

c) 24 976 ; 24 977 ; 24 978 ; 24 979 ; 24 980 ; 24 981 ; 24 982.

46:24+8:24

= ( 46+8):24

= 54:24

=2 ( dư 6)

705:45-336:45

= ( 705-336):45

= 369:45

= 8,8

dư 6 là sao hả bạn ? Có thể thành số thập phân đc mà
