question: John has 10 hectares of a pineapple field. There are 100 pineapples per hectare. John can harvest his pineapples every 3 months. How many pineapples can John harvest within a year?
answer: John has 100 x 10= <<100*10=1000>>1000 pineapples on his field.
  John can harvest his Pineapple 12 ÷ 3 = <<12/3=4>>4 times per year
  Therefore John can harvest 1000 x 4 = <<1000*4=4000>>4000 pineapples per year.
  #### 4000
