Question

a)  X + 3/5 x 2/3 = 2 - 1/5

b)  4/5 - X : 3/4 = 2/7 : 2

Answer 1

a) \(x+\frac{3}{5}\times\frac{2}{3}=2-\frac{1}{5}\)

\(x+\frac{2}{5}=\frac{9}{5}\)

\(x=\frac{9}{5}-\frac{2}{5}\)

\(x=\frac{7}{5}\)

b) \(\frac{4}{5}-x:\frac{3}{4}=\frac{2}{7}:2\)

\(\frac{4}{5}-x:\frac{3}{4}=\frac{2}{14}\)

\(x:\frac{3}{4}=\frac{4}{5}-\frac{2}{14}\)

\(x:\frac{3}{4}=\frac{23}{35}\)

\(x=\frac{23}{35}\times\frac{3}{4}\)

\(x=\frac{69}{140}\)

Answer 2

a)\(X+\frac{3}{5}.\frac{2}{3}=2-\frac{1}{5}\)

=>\(X+\frac{2}{5}=\frac{9}{5}\)

=>\(X=\frac{9}{5}-\frac{2}{5}\)

=>\(X=\frac{7}{5}\)

b)\(\frac{4}{5}-X:\frac{3}{4}=\frac{2}{7}:2\)

=>\(\frac{4}{5}-X:\frac{3}{4}=\frac{1}{7}\)

=>\(X:\frac{3}{4}=\frac{4}{5}-\frac{1}{7}\)

=>\(X:\frac{3}{4}=\frac{23}{35}\)

=>\(X=\frac{23}{35}.\frac{3}{4}\)

=>\(X=\frac{69}{140}\)
