Answer:

6 oranges

Step-by-step explanation:

4x125g= 500g

2x170g= 340g

3x135g= 405g

500+340+405= 1,245g

1.785kg= xg

1.785x1,000= 1,785g

1,785-1,245g= 540g

each orange weighs 90g

540/90= 6

Ken buys 6 oranges.

Considering the calculation of total weight of the fruit Ken bought, Ken buys 6 oranges.

Ken buys

  • 4 apples  weighing 125 g each
  • 2 bananas weighing 170 g each
  • 3 peaches weighing 135 g each
  • Each orange has a weight of 90 g.

So, the total weight of the fruit Ken bought is the sum between the weight of each fruit multiplied by the amount of that fruit bought:

4 apples× 125 g + 2 bananas× 170 g + 3 peaches× 135 g + amount of oranges× 90 g= total weight of fruit

The fruit has a total weight of 1.785 kg= 1785 g, being 1 kg=1000 g. So:

4 apples× 125 g + 2 bananas× 170 g + 3 peaches× 135 g + amount of oranges× 90 g= 1785 g

Solving:

500 g + 340 g + 405 g + amount of oranges× 90 g= 1785 g

1245 g + amount of oranges× 90 g= 1785 g

amount of oranges× 90 g= 1785 g - 1245 g

amount of oranges× 90 g= 540 g

amount of oranges= 540 g÷ 90 g

amount of oranges= 6

In summary, Ken buys 6 oranges.
