Question

Look at the middle 7 in the decimal 0.777. How is its value related to the value of the 7 to its left? To the value of the 7 to its right?

Answer 1

Answer:

Value of middle 7 = $\frac{1}{10}$(value of 7 to the left of the middle 7)

Value of middle 7 = $10$(value of 7 to the right of the middle 7)

Step-by-step explanation:

7 in the middle of number $0.777$ is equal to $\frac{7}{100}$

7 to the left of the middle 7 is equal to $\frac{7}{10}$

So,

$\frac{7}{100}=(\frac{1}{10}) \frac{7}{10}$

That is value of middle 7 = $\frac{1}{10}$(value of 7 to the left of the middle 7)

Also,

7 to the right of the middle 7 is equal to $\frac{7}{1000}$

So,

$\frac{7}{100}=(10) \frac{7}{1000}$

That is value of middle 7 = $10$(value of 7 to the right of the middle 7)
