Respuesta :

Using proportions, it is found that:

  • A regular chicken has a weight of 57.4 grams.
  • Coronavirus cases from US surpasses Guatemala by 81.63 times.

------------------------

  • These questions are solved by proportions, using rules of three.

------------------------

  • One feather has 0.0082 grams.
  • How many grams are there in 7000 feathers?

1 feather - 0.0082 grams

7000 feathers - x grams

Applying cross multiplication:

[tex]x = 0.0082 \times 7000 = 57.4[/tex]

A regular chicken has a weight of 57.4 grams.

------------------------

  • Considering the number of cases in Guatemala equivalent to 1, we find the ratio for the number of cases in the US.

490 000 - 1

40 000 000 - x

Applying cross multiplication:

[tex]490000x = 40000000[/tex]

[tex]x = \frac{40000000}{490000}[/tex]

[tex]x = 81.63[/tex]

Coronavirus cases from US surpasses Guatemala by 81.63 times.
