Let x = the number of boys.
Let y = the number of girls.
There are 48 children, therefore
x + y = 48 (1)
There are twice as many boys as girls, therefore
x = 2y (2)
Substitute (2) into (1).
2y + y = 48
3y = 48
y = 48/3 = 16
x = 2y = 2*16 = 32
x=32, y = 16
Answer: 16 girls
The value should be -49. Hope this helps.

Answer:
1/3 , 3/2 , 1/4 , 3/25 , 1/10 , 3/8 , 7/9 , 8/11
Step-by-step explanation:
* 9/27 ⇒ divide up and down by 9 ⇒ 1/3
* 12/8 ⇒ divide up and down by 4 ⇒ 3/2
* 2/8 ⇒ divide up and down by 2 ⇒ 1/4
* 6/50 ⇒ divide up and down by 2 ⇒ 3/25
* 1000/10000 ⇒ divide up and down by 1000 ⇒ 1/10
* 3/8 its simplest form (no common factor between 3 and 8)
* 7/9 its simplest form (no common factor between 7 and 9)
* 8/11 its simplest form (no common factor between 8 and 11)
