gì em

bài 1 :

a) \(\dfrac{1}{4}+\dfrac{15}{16}:\dfrac{3}{8}\cdot\dfrac{2}{3}=\dfrac{1}{4}+\dfrac{5}{2}\cdot\dfrac{2}{3}=\dfrac{1}{4}+\dfrac{10}{6}=\dfrac{6}{24}+\dfrac{40}{24}=\dfrac{23}{12}\)

b)A = 4,25 X (  58,47 + 41,53 ) - 125  = 4,25 x 100 - 125 = 425 - 125 = 300

53,5 = 4,25 x (  a + 41,53 ) - 125 

4,25 x ( a + 41,53 )  = 53,5 + 125 

4,25 x ( a + 41,53 ) = 178,5

a + 41,53                = 178,5 : 4,25

a + 41,53                =  42

a                              = 42 - 41,53

a                              = 0,47
