705 over 224 divide by 224 over 224
dybincka [34]
(705/224) / (224/224)
224/224 = 1.
So (705/224) / (224/224) = (705/224) / (1/1).
Dividing 2 fractions is equal to multiplying the first fraction by the inverse of the second:
(705/224) / (1/1) = (705/224) * (1/1) = 705/224.

Hope this Helps! :)

  • The vibrations causes movement of  the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.  
  • Also in the soil  is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
  • Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.
