Place is highest to lowest 3/4 84% 1/3 0.82

sesenic [268]

ANSWER

84%,0.82,¾,⅓

EXPLANATION

Convert everything to decimals.

$\frac{3}{4} = 0.75$

$84\% = 0.84$

$\frac{1}{3} = 0.333....$

The last one is already in decimals.

$0.82$

We can now see clearly, that

$0.84 \: > \: 0.82 \: > \: 0.75 \: > \: 0.3333...$

This implies that,

$84\% \: > \: 0.82 \: > \: \frac{3}{4} \: > \: \frac{1}{3}$

Hence from highest to least, we have

84%,0.82,¾,⅓

A sofa regularly sells for 860. The sale price is 670.80. Find the percent decrease of the sale price from the regular price

andre [41]

Answer:

-22%

Step-by-step explanation:

The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.

670.80 - 860 = -189.2

-189.2/860 = -0.22

-0.22*100 = -22%
