The numerator and the denominator of a certain fraction are consecutive odd numbers. if nine is subtracted from the numerator, the ratio of the numerator to the denominator of the new fraction is two to three. what is the original fraction? 1.) 21/33 2.) 31/33 3.) 30/32

 The correct option is (2)

Step-by-step explanation:  Given that the numerator and the denominator of a fraction are consecutive odd numbers.

Also, if nine is subtracted from the numerator, the ratio of the numerator to the denominator of the new fraction is two to three.

we are to find the fraction.

Let be the given fraction, where n is an integer.

Then, according to the given information, we have

Therefore, the required fraction will be

Thus, the fraction is

Option (2) is CORRECT.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
