David is considering changing his car to one which used liquefied petroleum gas (LPG). A litre of LPG costs £0.62 and a litre of petrol
costs £1.29. What is the cost of a litre of LPG as a percentage of the
cost of a litre of petrol (give your answer to the nearest whole number)?​

48%

Step-by-step explanation:

A liter of LPG costs £0.62

A liter of petrol costs £1.29.

Therefore,

The cost of a liter of LPG as a percentage of the cost of a liter of petrol is calculated as:

Cost of LPG/ Cost of Petrol × 100

= £0.62/£1.29 × 100

= 48.062015504%

Approximately to the nearest whole number = 48%

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
