If a kilo of fish is enough for 5 persons, how many grams of fish are needed for 20 visitors? At PhP130 a kilo, how much will be spent on fish?

Sagot :

We have the ratio:
1kg : 5 persons
So,
[tex] \frac{1kg}{5people} = \frac{xkg}{20people} \\ 20kg=5x \\ 4kg=x[/tex]

We convert this to grams with 1 kg = 1000g
[tex]4kg* \frac{1000g}{1kg} =4000g[/tex]

If we have P130 a kilo we just multiply this by 4 since we have 4kg.
[tex]4*P130=P520[/tex]
20 divided by 5=4 kg or 4,000 g

P 130 x 4=P 520

Hope this helps =)
