Title: Writing Fractions from Drawings - Fast And Easy Math Learning Videos
In this lesson you’ll learn to write the fraction that’s shown in a picture.
For example suppose you want to write the fraction shown by the shaded part of this picture. In this case the square is the whole.
And the whole is divided into 4 equal parts.
So 4 is our denominator.
3 of the parts are shaded.
So 3 is our numerator.
The shaded part of the picture shows three-fourths.
Let’s look at another example.
In this case the whole is the triangle.
The triangle has been divided into three parts.
However, the parts are not equal in size, so we can’t write a fraction from this picture. To write a fraction, the figure would have to be divided into equal-size parts.
Let’s look at another example.
In this case the whole is a circle.
Notice that we have two wholes shown.
The wholes are each divided into five equal parts.
So the denominator is 5.
7 of the parts are shaded
So the numerator is 7.
The shaded part of the picture shows seven-fifths.
Let’s look at one last example.
In this case the whole is a rectangle.
Notice that there are 4 wholes shown.
Each whole has been divided into three parts
So the denominator is three.
10 of the parts have been shaded in
So the numerator is 10.
The shaded part of the picture shows ten-thirds. In the remainder of this lesson you’ll write the fraction shown by the shaded part of a picture. Now do the rest on your own.
