Question

a; 3/8 + ( X -5/24 ) : 2/3 =1

b; 125 : X +375 : X - 200 : X = 12

Answer 1

a ) \(\frac{3}{8}+\left(x-\frac{5}{24}\right):\frac{2}{3}=1\)   |    \(\left(x-\frac{5}{24}\right):\frac{2}{3}=1-\frac{3}{8}=\frac{5}{8}\)

\(x-\frac{5}{24}=\frac{5}{8}\times\frac{2}{3}=\frac{10}{24}=\frac{5}{12}\)    |     \(x=\frac{5}{12}+\frac{5}{24}=\frac{15}{24}=\frac{5}{8}\)

b ) \(125\div x+375\div x-200\div x=12\)

\(\frac{125}{x}+\frac{375}{x}-\frac{200}{x}=12=\frac{300}{x}\)

\(x=300\div12=25\)
