there are 87 girls and 58 boys!

i divided 5 from 145 and got 29.
i multiplied 29 and 3 and got 87.
87 is the girls total.
then subtracted 87 from 145 and got 58.
58 is the boys total.


hope this helps!

Answer:

You Can do this in two ways. I will shaw both, the first one is more common and more easy :

Method 1:

  3/5 of 145 = girls  

  boys =  girls - boys  or 2/5

  3/5 x 145 = 87

  girls = 87

  boys = 145-87 = 58

Method 2:

  3/5 of 145 = girls

  boys =  girls - boys  or 2/5

  3/5 x 145 = 87

  girls = 87

   

   2/5 x 145 = 58

   boys = 58

Thank You
