Question

(1 14 + х): 1 45 -13=12

Answer 1

 

$(1frac{1}{4}+x):1frac{4}{5}-frac{1}{3}=frac{1}{2}$

 

$(frac{5}{4}+x):frac{9}{5}-frac{1}{3}=frac{1}{2}$

 

$(frac{5}{4}+x):frac{9}{5}=frac{1}{2}+frac{1}{3}$

 

$(frac{5}{4}+x):frac{9}{5}=frac{5}{6}$

 

$frac{5}{4}+x=frac{5}{6}*frac{9}{5}$

 

$frac{5}{4}+x=frac{9}{6}$

 

$x=frac{9}{6}-frac{5}{4}$

 

$x=frac{3}{12}$

 

$x=frac{1}{4}$

 

Answer 2

(1 14 + х): 1 45 -13=12

(1 14 + х): 1 45 =1/2+1/3

(1 14 + х): 1 45 =5/6

1 14 + х=5/6*9/5

1 14 + х=3/2

х=3/2-5/4

х=6/4-5/4

х=1/4
