AB=6cm

BC=6-4 =2 cm

= 16 cm

Pls help with the following question :




Apple + Apple + Orange = 330

And Orange + Orange + Apple = 210

What is the value of Apple + Orange = ?


thks

[PiggyLalala]

(Apple + Apple + orange) + ( orange + orange + apple ) = 330 + 210

therefore 3 apples + 3 oranges = 540
1 apple + 1 orange = 540/3
= 180

My DS at JEI PSLE Math. In the centre they use the torchlight method. E.g. You shine the torch light at one side, the sides shone is same as the opposite side.
