Answer from: rndschopplein

a. 5/30 and 1/6 ---> are equal

b.4/12 and 21/60 ---> are not equal

c. 17/34 and 41/82 ---> are equal

d. 6/9 and 25/36 ---> are not equal

Step-by-step explanation:

case a) we have 5/30 and 1/6

equate the fractions

$\frac{5}{30}=\frac{1}{6}$

using cross multiplication

(5)(6)=(30)(1)

30=30 ----> is true

therefore

The fractions are equal

case b) we have 4/12 and 21/60

equate the fractions

$\frac{4}{12}=\frac{21}{60}$

using cross multiplication

(4)(60)=(21)(12)

240=252 ----> is not true

therefore

The fractions are not equal

case c) we have 17/34 and 41/82

equate the fractions

$\frac{17}{34}=\frac{41}{82}$

using cross multiplication

(17)(82)=(41)(34)

1,394=1,394 ----> is true

therefore

The fractions are equal

case d) we have 6/9 and 25/36

equate the fractions

$\frac{6}{9}=\frac{25}{36}$

using cross multiplication

(6)(36)=(25)(9)

216=225 ----> is not true

therefore

The fractions are not equal

Answer from: chickennuggets0621

a. The fractions are equal.

b. The fractions are not equal

c. The fractions are equal.

d. The fractions are not equal

Step-by-step explanation:

By definition, equivalent fractions have the same value, but they look different.

In order to verify if two fractions are equivalent, you can use Cross multiplication.

The procedure is: multiply the numerator of the first fraction by the denominator of the second fraction, and the numerator of the second fraction by the denominator of the first fraction.

Then:

$a.\ \frac{5}{30}=\frac{1}{6}\\\\5*6=1*30\\\\30=30\ (The\ fractions\ are\ equal)$

$b.\ \frac{4}{12}=\frac{21}{60}\\\\4*60=21*12\\\\240=252\ (FALSE.\ The\ fractions\ are\ not\ equal)$

$c.\ \frac{17}{34}=\frac{41}{82}\\\\17*82=41*34\\\\1394=1394\ (The\ fractions\ are\ equal)$

$d.\ \frac{6}{9}=\frac{25}{36}\\\\6*36=25*9\\\\216=225\ (FALSE.\ The\ fractions\ are\ not\ equal)$

Answer from: Quest

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
