Using a system of equations, it is found that there were a total of 825,000 Arabic speakers, and the diagram is completed as follows:
- Smaller part: 825,000 - 639,000 = 186,000.
What is a system of equations?
A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
For this problem, the variables are given as follows, considering the situation described:
- Variable f: number of French Creole speakers.
- Variable a: number of Arabic speakers.
There were 639,000 French Creole speakers, hence:
f = 639,000.
There were 186,000 more Arabic speakers than French Creole speakers, hence:
a = 186,000 + f = 186,000 + 639,000 = 825,000.
There were a total of 825,000 Arabic speakers, and the diagram is completed as follows:
- Smaller part: 825,000 - 639,000 = 186,000.
