Answer

A. O.8743874374387438743....

Step by step explanation

Let's take a = O.8743874374387438743....

10a = 8.743874374387438743....

Similiarly,

10000a = 8743.874374387438743....

Since four decimal places are repeating.

Now subtract a from 10000a

10000 a - a = 8743.874374387438743.... - O.8743874374387438743....

9999 a = 8743

a = 8743/9999

8743/9999 = O.8743874374387438743....

That's it.

Hope you will understand the concept.

Thank you.

-Dominant- [34]

Answer:

3 daisies.

Step-by-step explanation:

Given that,

Samantha has 32 roses and 96 daisies.

She wants to make all the arrangements identical and have no flowers left over. We need to find the no of daisies in each flower arrangement.

For this, we need to first find the HCF of 32 and 96.

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

HCF = 32

No of daisies = 96/32 = 3

Hence, there are 3 daisies in each flower arrangement.
