Which arrangement shows 318 , 3.7, 334 , and 3.89 in order from least to greatest?
Stolb23 [73]

Answer: OPTION D.

Step-by-step explanation:

<h3> The complete exercise is: "Which arrangement shows 3\frac{1}{8}, 3.7, 3\frac{3}{4}, and 3.89 in order from least to greatest?"</h3><h3> </h3>

Convert from mixed numbers to decimal numbers.

The steps to do this, are the following:

1. You must divide the numerator of the fraction by the denominator.

2. Then you must add the quotient obtained to the whole number part.

Applying this procedure, you get that:

3\frac{1}{8}=3+0.125=3.125

3\frac{3}{4}=3+0.75=3.75

Now that you have all the numbers in decimal form, you can order from least to greatest:

3.125,\ 3.7,\ 3.75,\ 3,89

Therefore, you can conclude that the correct arrangement is:

3\frac{1}{8},\ 3.7,\ 3\frac{3}{4},\ 3,89
