20 cm by 16cm wide write the following ratio in simplified 1.length to width
20/16
divide top and bottom by 4
5/4
To write the ratio of length to width for a shape with dimensions 20 cm by 16 cm, we simply divide the length by the width.
The length is given as 20 cm, and the width is given as 16 cm.
So, the ratio of length to width is:
20 cm ÷ 16 cm.
To simplify this ratio, we can divide both the numerator and the denominator by their greatest common divisor (GCD) to obtain the simplest form.
To find the GCD of 20 and 16, we can list the factors of each number and find their greatest common factor:
Factors of 20: 1, 2, 4, 5, 10, 20
Factors of 16: 1, 2, 4, 8, 16
The GCD of 20 and 16 is 4.
Dividing both the numerator and the denominator by 4, we get:
20 ÷ 4 cm ÷ (16 ÷ 4) cm = 5 cm ÷ 4 cm.
So, the simplified ratio of length to width is 5:4.
