since 5×4 is in brackets, we start with that
so 2÷3 (20)÷3+6÷7

we do ×/÷ first from the left
so 4.44+ 0.8571428571 = 5.301
[tex] \frac{2}{3} * \frac{(5*4)}{3} + \frac{6}{7} = \frac{2}{3} * \frac{20}{3} + \frac{6}{7} = \frac{40}{9} + \frac{6}{7} = \frac{(40*7)+(6*9)}{9*7} = \frac{280+54}{63} = \frac{334}{63} [/tex][tex]=5.301587301587302[/tex] ≈ 5.30

Hence, the answer is 5.30
