\(\dfrac{2}{3}\) + \(\dfrac{8}{15}\) : \(\dfrac{16}{25}\) =

Answer 1

=2/3+8/15x25/16

=2/3+5/6=9/6=3/2

Answer 2

`2/3 + 8/15 : 16/25`

`= 2/3 + 5/6`

`= 3/2`.

Answer 3

3/2

Answer 4

= 2/3 + 5/6 = 3/2

Answer 5

2/3+8/15:16/25=2/3+8/15x25/16=2/3+5/6=4/6+5/6=9/6=3/2

Answer 6

2/3 + 8/15 : 16/25 = 2/3 + 25/30 = 20/30+ 25/30= 45/30

Answer 7

\(\dfrac{2}{3}+\left(\dfrac{8}{15}:\dfrac{16}{25}\right)=\dfrac{2}{3}+\left(\dfrac{8}{15}\times\dfrac{25}{16}\right)=\dfrac{2}{3}+\dfrac{200}{240}=\dfrac{2}{3}+\dfrac{5}{6}=\dfrac{4}{6}+\dfrac{5}{6}=\dfrac{9}{6}=\dfrac{3}{2}\)

Answer 8

3/2
