DAILY AND WEEKLY HORSES EXERCISE SCHEDULE IN MATHEMATICAL FRACTION



Whisper is a horse.


Mathematics Cambridge IGCSE Test (0580 m16 qp 32)

(a) Whisper eats three apples every day.
Work out how many apples she eats in 52 weeks.

Answer:
        
52 weeks  are same with 52 x 7 days = 364 days
She eats 3 apples x 364 days = 1092 apples.

(b) Whisper is exercised twice a day.
The first time is for 30 minutes.
The second time is for 1.5 hours.

(i) Write down the fraction of a day that Whisper is exercised.
Write your answer in its simplest form.

Answer:

Total time Whisper  do the exercise per day is 30 minutes + 1.5 hours,  will be equal to  2
hours.
The fraction of a day that Whisper is exercised is  2 / 24 hours per day, will be equal to   
1/12 day in the simplest form.

(ii) Write down the fraction of a day that she is not being exercised.

Answer:

The fraction of a day that she is not being exercised is 1 day is substracted by 1/12 day, will be equal  11/12 day.

(c) Whisper weighs 429 kg, correct to the nearest kilogram.
Complete the statement about her weight, w kg.

Answer:

Because of 429 kg is already rounded to the correct nearest kilogram,
the lower bound before 429 is rounded off is  equal to 428.5 or above.
And the upper bound before 429 is rounded off is below than 429.5, not equal to 429.5.
Because, if the value of w was equal to 429.5, it would be rounded off to 430 kg.
So the range value before 429 is rounded off are 428.5 ≤ w <  429.5

SIMILAR QUESTION (EXAMPLE QUESTION ONLY)

Bello is a male horse.

(a) Bello eats 0.7 pounds of pasture grass per hour.
Calculate how many pounds of pasture grass he eats in 56 hours.

Answer:

He eats 0.7 pounds of pasture grass x 56 hours =  39.2 pounds of pasture grass.

(b) Bello is exercised three times per week.
In one day, his first time exercise is for  45 minutes and his second time is for 1.5 hours.

(i) Write down the fraction of a week that Bello is exercised.
Give your answer in the simplest form.

Answer:

Total time Bello do the exercise per day is 45 minutes + 1.5 hours,  will be equal to  2 hours
and 15 minutes, or  2.25 hours.
The fraction of a day that Bello is exercised is  2.25 / 24 hours per day, will be equal to
9375/100000 day .
The fraction of a week that Bello is exercised is  7 days x 9375/100000, will be equal to  
65625/100000 week  or 21/32 week


(ii) Write down the fraction of a week that Bello is not being exercised.

Answer:

The fraction of a week that Bello is not being exercised is

1 week is substracted by 21/32 week, will be equal  11/32 week.


(c) Bello weighs  507,000 gr, correct to the nearest gram.
Complete the lower bound and upper bound about his weight, w gr.

Answer:

Because of 507,000 gr  is already rounded to the correct nearest  gram,
the lower bound before 507,000  is rounded off is  equal to 506,999.5 or above.
And the upper bound before 507,000 is rounded off is below than 507,000.5, not equal to  
507,000.5.
Because, if the value of w was equal to 507,000.5, it would be rounded off to 507,001 gr.
So the range value before 507,000 is rounded off are  506,999.5  ≤  w <  507,000.5
