Question

Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.28 cm to 40 cm00/0XS?ہے

Answer 1

The given terms are 28 cm and 40 cm

We will put 28 as a numerator and 40 as a denominator

`(28)/(40)`

Now, we will divide up and down by the greatest common factor of 28 and 40 to simplify the fraction

Since 28 = 1 x 28, 2 x 14, 4 x 7, then

The factors of 28 are 1, 2, 4, , 7, 28

Since 40 = 1 x 40, 2 x 20, 4 x 10, 5 x 8, then

The factors of 40 are 1, 2, 4, 5, , 8, , 10, 20, 40

The common factors of them are 1, 2, 4

The greatest one is 4

Divide up and down by 4

`\begin{gathered} (28)/(4)=7 \\ \\ (40)/(4)=10 \\ \\ (28)/(40)=(7)/(10) \end{gathered}`

The answer is 7/10
