Turn 0.272727... into a fraction

kherson [118]

Answer:

0.272727… = 27/99

Step-by-step explanation:

(since 27 is the repeating part of the decimal and it contains 2 digits). We can reduce this fraction (a process that we'll talk more about in a future article) by noticing that we can divide both the numerator and denominator by 9 to get 0.272727… = 27/99 = 3/11.

- Last week Shelley earned $60.00 in tips waitressing. This week she earned $72.00.

castortr0y [4]

Answer: 20%

Step-by-step explanation:

Rule of 3, let's put the money on the left and the percentage on the right of the chart.

$\frac{60.00}{72.00}=\frac{100}{x}$

$x=\frac{72*100}{60} \\x=120$

Calculate the difference.

$120-100=20$

An airplane flies 3800 km in 4 hours 45 minutes. What is its average speed in kilometers per hour?

8_murik_8 [283]

Average speed = (distance covered in some time) / (time to cover the distance)

4 hours 45 minutes = 4-3/4 hours = 4.75 hours

Average speed = (3,800 km) / (4.75 hours) = 800 km/hr
