Least to greatest 2/3, -2 2/5, 0.5, -0.8

-2 2/5, -0.8, 0.5, 2/3

Step-by-step explanation:

We have four values, two that are fractions and two that are decimals and are asked to put them from least to greatest.

We have a dillema of values in this question, two are fractions and two are decimals. We need to convert all of them towards one symbol to get our answer.

Let's try decimals, since they are more easier to see which is the bigger value.

Start with 2/3, what is 2 divided by 3?

2/3

0.6 repeated.

As of now, we have 0.6 repeated, -2 2/5, 0.5, and -0.8.

Now do the second fraction, turn -2 2/5 to an improper fraction by multiplying the whole number by the denominator and adding the numerator.

-2 * 5 + 2

-10 + 2

-8/5

Now convert -8/5 to a decimal :

-8/5

-1.6

Now we have all decimals, put the from least to greatest.

0.6 repeated, -1.6, 0.5, -0.8

-1.6, -0.8, 0.5, 0.6 repeated

Therefore our list from least to greatest is :

-2 2/5, -0.8, 0.5, 2/3

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
