There are 30 students in a class. One day, [tex]\frac{3}{5}[/tex] of them came without completing their mathematics homework. How many of them had completed their mathematics homework on that day?

Sagot :

To solve the problem of determining how many students completed their Mathematics homework, let’s break down the given information and find the solution step-by-step.

1. Total number of students in the class: 30

2. Fraction of students who came without completing their Mathematics homework: [tex]\(\frac{3}{5}\)[/tex]

3. Calculate the number of students who did not complete their homework:
This can be found by multiplying the total number of students by the fraction that did not do their homework:
[tex]\[ \text{Number of students without homework} = 30 \times \frac{3}{5} \][/tex]

4. Number of students without completing their Mathematics homework:
[tex]\[ 30 \times \frac{3}{5} = 18 \][/tex]
So, 18 students did not complete their homework.

5. Determine the number of students who completed their homework:
To find the number of students who completed their homework, we subtract the number of students who did not complete their homework from the total number of students:
[tex]\[ \text{Number of students with homework} = 30 - 18 \][/tex]

6. Final step: Calculate the number of students who completed their homework:
[tex]\[ 30 - 18 = 12 \][/tex]

Therefore, on that day, 12 students had completed their Mathematics homework.
