A box contains 4 red penciks and 6 black pencils what fraction of the pencils are red

4/10 .equals to 2/5.2/5 is a equivalent fraction

4/10 = 2/5

To find the fraction of red pencils, we need to divide the number of red pencils by the total number of pencils.

Given that there are 4 red pencils and 6 black pencils, the total number of pencils is 4 + 6 = 10.

The fraction of red pencils is therefore 4/10, which can be simplified to 2/5.

So, the fraction of the pencils that are red is 2/5.

To find the fraction of red pencils in the box, we need to divide the number of red pencils by the total number of pencils. Let's calculate it step by step.

Step 1: Find the total number of pencils.
In this case, the box contains 4 red pencils + 6 black pencils, which gives us a total of 10 pencils.

Step 2: Find the number of red pencils.
The box contains 4 red pencils.

Step 3: Calculate the fraction of red pencils.
To express this as a fraction, we put the number of red pencils (4) over the total number of pencils (10):

Fraction of red pencils = 4/10

So, the fraction of red pencils in the box is 4/10 or simplified as 2/5.
