Check Explanation

Step-by-step explanation:

The number line required to answer this question is missing.

But I'll explain how to get the total number of basketball cards Juan has, given the number that corresponds to 60% of the total number of cards.

Let the total number of basketball cards be x.

The first step is to check the number line presented. We furst require the number that corresponds to 60% of all of Juan's basketball cards..

Let us assume that the number of basketball cards according to the number line is 45.

This means that

60% of the total number of basketball cards = 45

60% × x = 45

0.6x = 45

x = (45/0.6) = 75 basketball cards.

So, the way to go is just to divide the number that the number line gives (which represents 60% of the total number of basketball cards) by 0.6 to obtain the total number of basketball cards.

Hope this Helps!!!
