6. Question 1Convert 0.47 into fraction.[Tukarkan 0.47 kepada pecahan. ]

To convert a decimal into a fraction, we need to determine the place value of the decimal. In this case, 0.47 has two decimal places. To convert it into a fraction, we write the decimal as the numerator and the denominator as a power of 10 based on the number of decimal places. Since there are two decimal places, the denominator will be 100. Therefore, 0.47 can be written as 47/100.

200g

20g

0.2g

The correct answer is 200g because it is the only option that is consistent with the given list of weights. The weights are listed in descending order, starting with the heaviest (2000g) and ending with the lightest (0.2g). Therefore, the next weight in the sequence would logically be 200g.

12. Question 3There are 40 packets of noodles in the school canteen. 12 packets of the noodles were sold during recess. Calculate the percentage of packets of noodles that were sold. [Terdapat 40 bungkus mi di sebuah kantin sekolah. 12 bungkus mi telah dijual pada waktu rehat. Hitungkan peratusan bungkusan mi yang telah dijual ]

12%

18%

22%

30%

The percentage of packets of noodles that were sold can be calculated by dividing the number of packets sold (12) by the total number of packets (40) and then multiplying by 100. This gives us (12/40)*100 = 30%.

17. Question 9There are m classes in STK programme. Each class has 25 students. Write an expression to represent the total number of students in the programme.[Terdapat m buah kelas di Program STK. Setiap kelas ada 25 orang pelajar. Tulis ungkapan yang mewakili jumlah pelajar bagi program tersebut.]

The expression to represent the total number of students in the programme is 25m. This is because there are m classes and each class has 25 students. By multiplying the number of classes (m) by the number of students in each class (25), we can find the total number of students in the programme.

19. Question 4Which of the following is the measurement of Metric System?[Yang manakah di antara berikut merupakan pengukuran bagi Sistem Metrik? ] i.Ounces (oz) ii.pounds (lb) iii.gramme (g) iv.kilogramme (kg)

I and ii

I and iii

Ii and iii

Iii and iv

The correct answer is "iii and iv". This is because the metric system primarily uses the gram (g) as a unit of measurement for weight, and the kilogram (kg) as a larger unit of measurement. Ounces (oz) and pounds (lb) are not part of the metric system.
