Explain (in words) what you would do to find the missing value in the equation. You do not find the missing number! Equation: ?

maks197457 [2]

Answer:

The missing value = $23\frac{1}{24}$

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + $59\frac{5}{8}$ = $82\frac{2}{3}$

⇒x = $82\frac{2}{3}$ - $59\frac{5}{8}$

= $\frac{248}{3} - \frac{477}{8}$

= $\frac{1984 - 1431}{24}$

= $\frac{553}{24}$

= $23\frac{1}{24}$

⇒x = $23\frac{1}{24}$

∴ we get

The missing value = $23\frac{1}{24}$

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.

2.67 repeating as a fraction in simplified

maksim [4K]

Answer:

$2.\overline {67}=\frac{265}{99}$

Step-by-step explanation:

Given

$2.\overline {67}$

Let

$x=2.\overline {67}$

$x=2.676767...$

$100x=100(2.676767...)$

$100x=267.6767...$

$100x=265+2.6767...$

$100x=265+x$

$99x=265$

$x=\frac{265}{99}$

Therefore,

$2.\overline {67}=\frac{265}{99}$
