What part of the whole does the shaded (blue) area represent?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Upon examining the diagram, we observe that the grid is divided into 10 vertical sections. Each section is presumably equal in area.
Step 2: There is 1 shaded section, which is the first vertical column on the left.
Step 3: Using the fraction formula, the part of the whole represented by the shaded section is , because there is 1 shaded section out of 10 total sections.
Step 4: We convert the fraction into its decimal form, which is .
Therefore, the solution to the problem is the shaded area represents or of the whole.
This corresponds to choice 3: and .
and
Write the following fraction as a decimal:
\( \frac{5}{100}= \)
Both forms represent the same value but are useful in different situations! Fractions like show the exact relationship, while decimals like 0.1 are easier for calculations and comparisons.
Look for the grid lines that divide the shape into equal parts. In this problem, there are 10 vertical columns, so the total is 10. Count carefully and make sure all sections are the same size!
Just count all the shaded sections for your numerator! If 3 out of 10 sections were shaded, the answer would be or 0.3.
is already in its simplest form because 1 and 10 share no common factors other than 1. You cannot reduce it further!
Simply divide the numerator by the denominator! For example: . Use long division if needed.
