Question

a) 3,37 + X = 76,8 

b) x - 34,8 = 4,56 + 8,44 

c) 8,2 x X = 28,7 

d) 45 ,56 - x = 23 ,8 

đ) 25 : x = 1,6 

e) x : 3,2 =8,25

Answer 1

a) 3,37 + X = 76,8 

X = 76,8 - 3,37

X = 73.43

b) x - 34,8 = 4,56 + 8,44 

 x - 34,8 = 13

x = 13 + 34,8 

x = 47.8

c) 8,2 x X = 28,7 

x = 28,7 : 8,2

x = 3.5

d) 45 ,56 - x = 23 ,8 

x  = 45,56 - 23,8

x = 21.76

đ) 25 : x = 1,6 

x = 25 : 1,6

x = 15.625

e) x : 3,2 =8,25

x = 8,25 x 3,2

x = 26.4

Answer 2

\(a,x=76,8-3,37\)

\(x=73,43\)

\(b,x-34,8=13\)

\(x=13+34,8\)

\(x=47,8\)

\(c,x=28,7:8,2\)

\(x=3,5\)

\(d,x=45,56-23,8\)

\(x=21,76\)

\(đ,x=25:1,6\)

\(x=15,625\)

\(e,x=8,25\times3,2\)

\(x=26,4\)

Answer 3

a) 3,37 + X = 76,8 

X = 76,8 - 3,37

X = 73.43

b) x - 34,8 = 4,56 + 8,44 

 x - 34,8 = 13

x = 13 + 34,8 

x = 47.8

c) 8,2 x X = 28,7
