Question

9.) HCF of 2.5, 0.75 and 5 is​

Answer 1

H.C.F = $\frac{1}{20}$

Step-by-step explanation:

Given,Numbers are 2.5,0.75 and 5

These numbers can also be written as $\frac{25}{10}, \frac{75}{100}, \frac{5}{1}$

We know that ,

H.C.F of fraction = $\frac{H.C.F\ of\ numerator}{L.C.M\ of\ denominator}$

                           =$\frac{H.C.F\ of\25,75,5}{L.C.M\ of\ 10,100,1}}$

                           = $\frac{5}{100}$

                           =$\frac{1}{20}$

Answer 2

The H.C.F. of  2.5, 0.75 and 5  is 0.25.

Step-by-step explanation:

Consider the provided numbers.

We need to calculate the HCF of 2.5, 0.75 and 5.

First convert each of the number into like decimals.

2.50, 0.75 and 5.00

Remove the decimal point and represent each number as the sum of primes without the decimals.

250 = 2 × 5 × 5 × 5

75 = 3 × 5 × 5

500 = 2 × 2 × 5 × 5 × 5

The H.C.F. of 250, 75 and 500 = 5 × 5 = 25

Place the decimal point as there are several decimal positions in the same decimal places.

Therefore, the H.C.F. of  2.50, 0.75 and 5.00  = 0.25
