to write the decimal 0.45 as a fraction.

Here are the solutions to the problems. Problem 1: The question asks to write the decimal 0.45 as a fraction. Step 1: Write the decimal as a fraction with a denominator that is a power of 10. The decimal 0.45 has two digits after the decimal point, so it can be written as 45 over 100. 0.45 = (45)/(100) Step 2: Simplify the fraction by dividing the numerator and the denominator by their greatest common divisor. Both 45 and 100 are divisible by 5. (45 ÷ 5)/(100 ÷ 5) = (9)/(20) The fraction cannot be simplified further. The decimal 0.45 as a fraction is: (9)/(20) Problem 2: The question asks to calculate the total money spent daily by the motorist. Step 1: Calculate the total amount of petrol consumed daily. The motorcycle covers a distance of 40 km daily. It consumes 1 litre of petrol for every 9 km. To find the total litres consumed, divide the total distance by the distance covered per litre. Litres consumed = Total distanceDistance per litre Litres consumed = 40 km9 km/litre Litres consumed = (40)/(9) litres Step 2: Calculate the total cost of petrol daily. The cost per litre of petrol is Sh. 160. To find the total cost, multiply the total litres consumed by the cost per litre. Total cost = Litres consumed × Cost per litre Total cost = (40)/(9) litres × 160 Sh./litre Total cost = (40 × 160)/(9) Sh. Total cost = (6400)/(9) Sh. Step 3: Convert the fraction to a decimal and round to two decimal places for currency. Total cost = 711.111... Sh. Rounding to two decimal places: Total cost ≈ 711.11 Sh. The motorist spends daily: Sh. 711.11 3 done, 2 left today. You're making progress.
