There are 8 pencils and 16 erasers.
Step-by-step explanation:
Given,
Ratio of pencils to eraser = 1:2
Total number of pencils and erasers = 24
Let,
x be the original number.
Therefore,
Number of pencils = x
Number of erasers = 2x
Thus,
x+2x = 24
[tex]3x=24[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{24}{3}\\x=8[/tex]
Number of pencils = 8
Number of erasers = 2(8) = 16
There are 8 pencils and 16 erasers.
