Question

For her new MP3 player, Alicia wants a case that is 3 2/5 in. long. The online store shows case sizes in decimal measurements. What length case should she order?

Answer 1

To find the length case Alicia should order, convert the mixed number 3 2/5 to a decimal by adding the whole number part to the decimal equivalent of the fraction part. The result is 3.4 inches.

Step-by-step explanation:

To find the length case Alicia should order, we need to convert the mixed number 3 2/5 to a decimal. We can do this by adding the whole number part (3) to the fraction part (2/5) as a decimal.

To add the fraction part as a decimal, we divide 2 by 5: 2 ÷ 5 = 0.4

Adding the whole number and fraction parts together, we get: 3 + 0.4 = 3.4

Therefore, Alicia should order a case that is 3.4 inches long.
