Answer:
Step-by-step explanation:
1.3 Round off the number 2 438 to the nearest thousand.
To round 2,438 to the nearest thousand, we look at the hundreds place:
The hundreds place digit is 4.
Since 4 is less than 5, we round down.
Therefore, rounding 2,438 to the nearest thousand gives us 2,000.
1.5 Value Added Tax (VAT) is at 15%. Convert 15% to a decimal fraction.
To convert 15% to a decimal fraction, you divide by 100:
15
%
=
15
100
=
0.15
15%=
100
15
=0.15
So, 15% as a decimal fraction is 0.15.
1.4 A taxi needs 118 liters of fuel for a single trip from Louis Trichardt to Bloemfontein. Calculate how much fuel the taxi will use for four single trips.
If the taxi uses 118 liters for a single trip, then for four trips:
Fuel for four trips
=
118
×
4
Fuel for four trips=118×4
Fuel for four trips
=
472
liters
Fuel for four trips=472 liters
Therefore, the taxi will use 472 liters of fuel for four single trips.
1.5 A group of friends participated in the Zama-Zama relay competition and completed a total distance of 900 m. Each one of them ran a distance of 150 m. How many friends participated in the competition?
Let
N be the number of friends participating.
Total distance covered by all friends =
×
150
N×150 m.
According to the problem, the total distance is 900 m.
So, we set up the equation:
×
150
=
900
N×150=900
To find
N, divide both sides by 150:
=
900
150
N=
150
900
=
6
N=6
Therefore, 6 friends participated in the competition.
1.6.1 The ratio of male students to female students in MLMS4 class is 3:4. If there are 15 male students in the class, calculate the number of female students.
Let
x be the number of female students.
Given the ratio of male to female students is 3:4, and there are 15 male students, we can set up the proportion:
15
=
3
4
x
15
=
4
3
Cross-multiply to solve for
x:
3
=
4
×
15
3x=4×15
3
=
60
3x=60
Divide both sides by 3 to solve for
x:
=
60
3
x=
3
60
=
20
x=20
So, there are 20 female students in the class.
1.6.2 Hence determine the total number of students in the class.
Now that we know there are 15 male students and 20 female students, we can find the total number of students:
Total number of students = Number of male students + Number of female students
Total number of students
=
15
+
20
Total number of students=15+20
Total number of students
=
35
Total number of students=35
Therefore, the total number of students in the MLMS4 class is 35.
