Question

a) ` (1/2 - 3/4)^2 : 7/16 + 3/5`

Answer 1

\(=\left(-\dfrac{1}{4}\right)^2:\dfrac{7}{16}+\dfrac{3}{5}=\dfrac{1}{16}:\dfrac{7}{16}+\dfrac{3}{5}=\dfrac{1}{7}+\dfrac{3}{5}=\dfrac{26}{35}\)

Answer 2

a)

\(\left(\dfrac{1}{2}-\dfrac{3}{4}\right)^2:\dfrac{7}{16}+\dfrac{3}{5}\)

\(=\left(\dfrac{2}{4}-\dfrac{3}{4}\right)^2:\dfrac{7}{16}+\dfrac{3}{5}\)

\(\left(-\dfrac{1}{4}\right)^2:\dfrac{7}{16}+\dfrac{3}{5}\)

\(=\dfrac{1}{16}.\dfrac{16}{7}+\dfrac{3}{5}\)

\(=\dfrac{1}{7}+\dfrac{3}{5}\)

\(=\dfrac{5}{35}+\dfrac{21}{35}\)

\(=\dfrac{26}{35}\)

Answer 3

=26/35
