Question

there are 24 pencils in a box.
1 upon 8 of them are sharp. how many pencils are not sharp.​

Answer 1

Answer:

21

Step-by-step explanation:

1 in 8 pencils if sharp means 1/8 of the pencils are sharp. If we convert it to an equilateral fraction with the denominator as 24, The fraction of sharp pencils would become 3/24.

No. of Pencils= 24

Fraction of Pencils=24/24

Fraction of Sharp Pencils= 3/24

Fraction of Pencils not sharp= 24/24 - 3/24

                                               = 21/24

Therefore, 21 pencils are not sharp

Answer 2

Given,

There are $24$ pencils in a box.

The sharp pencils $=$ $1$ upon $8$ of them are sharp

So,

Sharp pencils $= \frac{1}{8}\times24$

Sharp pencils $=3$

Not sharp pencils $=$ total number of pencils $-$Number of sharp pencils

$= 24-3$

$=21$

Therefore, the $21$ pencils are not sharp.
