8 possible numbers remain for position 2 (10 minus 2 already selected)

The denominator of a rational numbers is twice it’s numerator if the numerator is decreased by 3 and the denominator increased b

ASHA 777 [7]

Answer:

$\frac{29}{58}$

Step-by-step explanation:

let x be the numerator of the rational number then 2x is the denominator

original fraction = $\frac{x}{2x}$

subtracting 3 from numerator and adding 7 to denominator , gives

$\frac{x-3}{2x+7}$ = $\frac{2}{5}$ ( cross- multiply )

5(x - 3) = 2(2x + 7) ← distribute parenthesis on both sides )

5x - 15 = 4x + 14 ( subtract 4x from both sides )

x - 15 = 14 ( add 15 to both sides )

x = 29

rational number = $\frac{29}{58}$

Firlakuza [10]

Given :

On average, a refrigerator door is opened 99 times each day.

Len has two refrigerators in his house.

To Find :

How many times in a 8−week period are the refrigerator doors opened.

Solution :

Number of times door opened for 2 refrigerator , n = 99×2 = 198.

Number of days in 8 week , d = 8×7 = 56 days.

So, total number of times doors open in a period of 8-week is :

$T=n\times d\\\\T=198\times 56\\\\T=11088\ times$

Therefore, refrigerator doors are opened about 11088 times.

Hence, this is the required solution.
