Answer:
Number of girls = 45
Step-by-step explanation:
No. of girls be = X
N. of boys = 2/5 of X(girls)
Total no.of students = 63
Thus equation for above
= X+2/5*X = 63
= 5X/5 + 2X/5 = 63
= 7X/5= 63
= X= 63*5/7
= X= 9*5
X= 45
X = No. of girls
thus 45 is the number of girls and 18 is the number of boys.
