\(2018.\frac{1212}{2424}=2018.\frac{1212:1212}{2424:1212}=2018.\frac{1}{2}=1009\)

~Study well~

Trả lời:

2018 * ( 1212/2424 )

= 2018 * 1/2

= 1009

~~GOD~~

\(2018x\frac{1212}{2424}=2018x\frac{1212:1212}{2424:2424}=2018x\frac{1}{2}=1009\)

HÃY LUÔN ;-)

Ta có:

  \(\frac{1212}{2424}=\frac{1}{2}\)

\(\Rightarrow2018.\left(\frac{1}{2}+\frac{1}{2}\right)=2018.1=2018\)

chia 101/101 để ra được 1/2

\(\dfrac{1}{3}+\dfrac{6}{5}-\dfrac{1}{5}+\dfrac{2}{3}=2\)

1/3+6/5−1/5+2/3=2

120 ****

2 x 3 x 4 x 5 

= 6 x 20 

= 120 

=[ 2 x 5 ] x [ 3 x 4 ]

= 10 x 12

= 120

1212/1515 = 1212 :1515 

= 12 x 101 : 15 x 101 

= 12/15

dinh hoang vu

\(\frac{1212}{1515}=\frac{1212\div101}{1515\div101}\)

\(=\frac{12}{15}=\frac{4}{5}\)

\(\frac{1212}{1515}=\frac{2^2.3.101}{3.5.101}=\frac{2^2}{5}=\frac{4}{5}\)

50056456+(56442424455x2)=50056456+112884848910

                                         =112934905366

2,5 x 12 ,5 x 8 x 0,4=(2,5 x 0,4 ) x(12,5 x8)

                            =1x100=100

=2,5 x 12,5 x 8 x 0,4

=(2,5 x 0,4) x (12,5 x 8)

=1 x 100

=100

Tính bằng cách thuận tiện nhất: 2,5x12,5x8x0,4=100

k mik nha

  25x20x125x8-8x20x5x125

=(25x8)x(20x125)-(20x5)x(8x125)

=200x2500-100x1000

=500000-100000=400000

mk tính giống bạn kia
