Question

tính

a) 23,56 + 6,8 : 0,4

b) 7/8 : X = 11/12

Answer 1

\(a,23,56+6,8:0,4\)

\(=23,56+17=40,56\)

\(b,\dfrac{7}{8}:x=\dfrac{11}{12}\)

\(x=\dfrac{7}{8}:\dfrac{11}{12}\)

\(x=\dfrac{21}{22}\)

Answer 2

a/=23.56+7.2

=30.76

b/x=7/8:11/12

X=7/8X12/11

=84/88=21/22

Answer 3

a) 23,56 + 6,8 : 0,4

= 23,56 + (6,8 : 0,4)

= 23,56 + 17

= 40,56

b) 7/8 : X = 11/12

x = 7/8 :11/12

x = 21/22

Answer 4

a=30,56

b=21/22
