Answer :

The answers to all the subparts are shown:

  • (A) Using the conversion factor we know that the consumption of fuel was 26 liters.
  • (B) Giorgio spends €87 on 60 liters of fuel.
  • (C) Giorgio can buy 40 liters of fuel for € 58

What is the conversion factor?

  • A conversion factor is a number that is used to multiply or divide one set of units into another.
  • If a conversion is required, it must be done using the correct conversion factor to get an equal value.
  • For instance, 12 inches equals one foot when converting between inches and feet.

(A) So, we know that: 1 liter = 10 decilitre

  • Similarly, 60 liter = 600 decilitre
  • Then, 340 decilitre = 34 liter

So, the consumption of the fuel = 60 - 34 = 26 litres.

(B) Cost of 60 liters of fuel if 1 liter is € 1.45:

  • 60 × 1.45 = €87
  • Giorgio spends €87 on 60 liters of fuel.

(C) Liters of fuel he could buy from € 58:

  • 58/1.45 = 40 litres
  • He can buy 40 liters of fuel for € 58

Therefore, the answers to all the subparts are shown:

  • (A) Using the conversion factor we know that the consumption of fuel was 26 liters.
  • (B) Giorgio spends €87 on 60 liters of fuel.
  • (C) Giorgio can buy 40 liters of fuel for € 58
