C1 : 5/24 x 5/12 x 24
= 5/24 x ( 5/12 x 24 )
= 5/24 x 10
= 50/24
= 25/12
C2 : 5/24 x 5/12 x 24
= ( 5/24 x 24 ) x ( 5/12 )
= 5 x ( 5/12 )
= 25/12
Chúc em học giỏi !!!
Cách 1 : 5/24 x 5/12 x 24 = (5/24 x 24) x 5/12
= 5 x 5/12 = 25/12
Cách 2 : 5/24 x 5/12 x 24 = 5/24 x (5/12 x 24)
= 5/24 x 10 = 25/12
c1
5/24x5/12x24
=5/24x(5/12x24)
=5/24x10
=50/24
=25/12
c2
5/24x5/12x24
=(5/24x24)x5/12
=5x5/12=25/12
~~ học tốt nhé!!
24 = x + 5 : 5
C1 : 5/24 x 5/12 x 24
= 5/24 x ( 5/12 x 24 )
= 5/24 x 10
= 50/24
= 25/12
C2 : 5/24 x 5/12 x 24
= ( 5/24 x 24 ) x ( 5/12 )
= 5 x ( 5/12 )
= 25/12
