oblicz według wzoru plz szybko​

Answer 1

Odpowiedź:

a)   4/3 x +5/8x= ( 4/3 +5/8)x= ( 32/24 +15/24)x=47/24 x= 1 i 23/24x

b)   1,2 x  + 2/3 x= ( 1,2 + 2/3 )x= ( 1 i 2/10 + 2/3)x= ( 1 i 6/30 + 20/30)x=

              = 1 i 26/30 x   = 1 13/15 x

c) 1/4 x +5/6x =1/2 x)=  ( 1/4 + 5/6 -1/2)x= ( 3/12 + 10/12 - 6/12)x= 7/12 x

d)   3/7 x -0,2 x +x= ( 3/7 - 2/10 +1)x= ( 30/70 - 14/70 +1)x=( 16/70+1 )x=

                    =  1 i 16/70 x= 1 i 8/35 x

Szczegółowe wyjaśnienie:

Answer 2

a) = (12/24 + 8/24)x= 20/24x

b) = ( 12/10 + 2/3)x = (15/30 + 12/30)x = 27/30x

c) = (7/24 + 9/24 + 13/24)x= 29/24 x

d) ( 3/7 - 2/10 + x ) x = (13/70 - 9/70 + x ) x = 4/70 x2
