Is the fraction 1/3 equivalent to a terminating decimal or a decimal that does not terminate
umka21 [38]
<span>1/3 is equivalent to a decimal that does not terminate. A terminating decimal is one that ends. Some decimals never end, however. If you divide 1 by 3 using the standard algorithm, you will get 0.333333... repeating forever. This is a non-terminating decimal, or repeating decimal. In contrast, 1/4 is equal to 0.25, which is a terminal decimal.</span>

What is 3 divided by 2/3 x 3? <br><br> please show work!
IgorC [24]

<u>Answer:</u>

<em>The correct answer is 1 1/2</em>

<u>Step-by-step explanation:</u>

<em>First, We need to find out the sum of 2/3  x 3, change 3 into a fraction if you want</em>

<em>3x2=6 and 1x3 is 3, So 2/3 x 3 is 6/3 or 2</em>

<em>Next, divide 3 by 2, change to fractions if needed</em>

<em>Remember keep, change and flip, flip 2/3 to 1/2</em>

<em>Then, you multiply 3/1 and 1/2 3x1=3 1x2=2</em>

<em>Finally divide 3 by 2. 3  ÷ 2 is 1 1/2</em>

<em>I hope this helped!</em>
