Martha's claim that the 25% of the learners are girls, is correct.
In this question,
There are 900 boys and 300 girls at Eqinisweni secondary school.
Martha claims that 25% of the learners are girls.
We need to verify her claim by means of calculations.
Based on the given conditions, we formulate:
300 / (900 + 300)
We simplify above expression.
= 300 / 1200
= 1/4 ..................(Cross out the common factor)
Now multiply a number 25 to both the numerator and the denominator:
= (1 × 25)/(4 × 25)
= 25/200
Now we rewrite a fraction with denominator equals 100 to a percentage: 25%
This means, Martha's claim that the 25% of the learners are girls, is correct.
