In a shool,7/10 of the pupils like mathematics.Half of those pupils who like mathematics are girls.If there areither 240 pupIlsley altogether in the school,how many girls like mathematics.
girls who loved maths=½(7/10)×240=
To find the number of girls who like mathematics, we need to follow these steps:
Step 1: Calculate the total number of students who like mathematics. We know that 7/10 of the students like mathematics, so we can find this by multiplying the total number of students by 7/10:
Total students who like mathematics = Total number of students × 7/10
Given the total number of students is 240, we can substitute that into the equation:
Total students who like mathematics = 240 × 7/10
Step 2: Calculate the number of students who are girls and like mathematics. We are told that half of the students who like mathematics are girls, so we need to find half of the total number of students who like mathematics:
Girls who like mathematics = Total students who like mathematics × 1/2
Substituting the value we found in step 1:
Girls who like mathematics = (240 × 7/10) × 1/2
Now we can do the calculations and find the answer:
Girls who like mathematics = 168 × 1/2
Girls who like mathematics = 84
Therefore, there are 84 girls in the school who like mathematics.
