In a school 4/11 of the students are girls.if there are 490 boys, find the number of girls.
Wrong answer
Thanks
To find the number of girls, we need to determine the total number of students in the school.
Let's start by finding the fraction of boys. We know that 4/11 of the students are girls, which means the remaining 7/11 must be boys.
If we have 7/11 of the total number of students representing 490 boys, we can set up a proportion to find the total number of students:
(7/11) = 490/T
Where T represents the total number of students.
To solve for T, we can cross-multiply:
7T = 11 * 490
7T = 5390
T = 5390/7
T ≈ 770
Therefore, the total number of students in the school is approximately 770.
Now, to find the number of girls, we can multiply the total number of students by the fraction of girls:
Number of girls = (4/11) * 770
Number of girls ≈ 280
Hence, there are approximately 280 girls in the school.
Fujf
Yes
number of students ---- x
(7/11)x =490
x =490(11/7) = ...
then take 4/11 of that
