Question

5/9:4/7+13/19*7/4

Answer 1

\(\dfrac{5}{9}:\dfrac{4}{7}+\dfrac{13}{19}\times\dfrac{7}{4}\)

\(=\dfrac{5}{9}\times\dfrac{7}{4}+\dfrac{13}{19}\times\dfrac{7}{4}\)

\(=\dfrac{7}{4}\times\left(\dfrac{5}{9}+\dfrac{13}{19}\right)\)

\(=\dfrac{7}{4}\times\dfrac{212}{171}\)

\(=\dfrac{371}{171}\)

Answer 2

=7/4(5/9+13/19)

=7/4*212/171

=371/171

Answer 3

\(\dfrac{5}{9}:\dfrac{4}{7}+\dfrac{13}{19}\times\dfrac{7}{4}\)

\(=\dfrac{5}{9}\times\dfrac{7}{4}+\dfrac{13}{19}\times\dfrac{7}{4}\)

\(=\left(\dfrac{5}{9}+\dfrac{13}{19}\right)\times\dfrac{7}{4}\)

\(=\dfrac{212}{171}\times\dfrac{7}{4}\)

\(=\dfrac{371}{171}\)

Answer 4

    \(\dfrac{5}{9}\): \(\dfrac{4}{7}\) + \(\dfrac{13}{19}\) \(\times\) \(\dfrac{7}{4}\)

= \(\dfrac{5}{9}\) \(\times\) \(\dfrac{7}{4}\) + \(\dfrac{13}{19}\) \(\times\) \(\dfrac{7}{4}\)

= \(\dfrac{7}{4}\) \(\times\) ( \(\dfrac{5}{9}\) + \(\dfrac{13}{19}\))

= \(\dfrac{7}{4}\) \(\times\) ( \(\dfrac{95}{171}\) + \(\dfrac{117}{171}\))

= \(\dfrac{7}{4}\) \(\times\) \(\dfrac{212}{171}\)

= \(\dfrac{371}{171}\)
