A survey published by the Department of Education reported on the number of schools, learners and teachers in ordinary public schools and independent schools during 2013 - NSC Mathematical Literacy - Question 5 - 2017 - Paper 1

To find the total number of teachers, sum all the teachers across the provinces:

$66 007 + 24 475 + 74 823 + 96 057 + 57 108 + 34 936 + 8 972 + 26 194 + 36 451 = 425 023$

Thus, the total number of teachers in South Africa for 2013 is 425,023.

To calculate the percentage of schools in KwaZulu-Natal, use the formula:

$\text{Percentage of schools} = \left(\frac{\text{Number of schools in KZN}}{\text{Total number of schools}}\right) \times 100$

Assuming the number of schools in KZN and the total is known, replace the values and calculate.

Using the provided formula:

$\text{LSR} = \frac{\text{Total number of learners in Gauteng}}{\text{Total number of schools in Gauteng}}$

Replace the numbers from table 3 to find LSR.

For the modal ratio:

(a) The modal ratio is the most frequently occurring ratio among the provinces.

(b) To arrange the ratios in descending order, sort them from highest to lowest value.

(c) The median ratio can be found by listing the ratios in order and finding the middle value.

Utilize the provided Teacher-School Ratios (TSR) to accurately draw the bars representing each province's ratio on the bar graph.
