Enter your answer as a simplified fraction formatted like this: 42/53
expeople1 [14]

Answer:

\displaystyle -0.\overline{37}=-\frac{37}{99}

Step-by-step explanation:

<u>Convert a Repeating Decimal to a Fraction </u>

We need to convert the following decimal to a fraction:

-0.\overline{37}

Let's call x to the given number:

x=-0.\overline{37}

The number has two repeating (periodic) decimals, thus we multiply by 100:

100x=-37.\overline{37}

Note the decimals continue to repeat exactly like the original number.

Subtracting both expressións, the repeating decimals are simplified:

100x - x = -37

Operating:

99x=-37

Dividing by 99:

\displaystyle x=-\frac{37}{99}

The fraction cannot be simplified, thus:

\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}

What is 0.353 rounded to the nearest tenth
KengaRu [80]
0.4 .

Explanation
Rounding to the tenth, you look at the 2nd number after the period, if it’s greater than 5 or 5 itself u and 1 to the first number after the period. Back to the question 0.353 , the 2nd number after the period is 5, so u add 1 to the 1st number after the period with it’s 3 and 3+1=4. If you are rounding to tenth only leave one number after the period with gives you 0.4. Hopefully you get it.
