Prove algebraically that the recurring decimal 0.472 can be written as 17 36

Katen [24]

Given:

The recurring decimal is $0.47\overline{2}$ .

To prove:

Algebraically that the recurring decimal $0.47\overline{2}$ can be written as $\dfrac{17}{36}$ .

Proof:

Let,

$x=0.47\overline{2}$

$x=0.472222...$

Multiply both sides by 100.

$100x=47.2222...$ ...(i)

Multiply both sides by 10.

$1000x=472.2222...$ ...(ii)

Subtract (i) from (ii).

$1000x-100x=472.2222...-47.2222...$

$900x=425$

Divide both sides by 900.

$x=\dfrac{425}{900}$

$x=\dfrac{17}{36}$

So, $0.47\overline{2}=\dfrac{17}{36}$ .

Hence proved.

lara31 [8.8K]

The missing weights are:

2 2 2 1 11 12 12 2 24 22 24 3 37 22

Answer:

$Average = 12\frac{4}{7} \ lb$

Step-by-step explanation:

Given

Weight of sea glass

To solve this question, we have to calculate the mean of the weight of the sea glass as follows;

$Average = \frac{\sum x}{n}$

Where n = number of sea glass

$n = 14$

So:

$Average = \frac{\sum x}{n}$ becomes

$Average = \frac{2 +2 + 2 + 1 + 11 +12 +12 +2 +24+22 +24 +3 +37+ 22}{14}$

$Average = \frac{176}{14}$

$Average = 12\frac{8}{14}$

Simplify fraction

$Average = 12\frac{4}{7}$

Hence; the weight of the sea glass would be $12\frac{4}{7}\ lb$ when evenly distributed...
