Answer:

7/14 and 20/40 are proportional.

Step-by-step explanation:

We're looking for the pairs of ratios where the two ratios are equal.

6/21 and 2/42 are not equal, although 6/21 and 12/42 would be equal.

25/100 and 50/150 are not equal.

18/24 and 6/12 are not equal.  Notice that dividing 18 and 24 by 6 results in 3/8, which does not equal 6/12 or 3/6 or 1/2.

In the last case, notice that 7/14 = 1/2 and 20/40 = 1/2.  This pair of fractions is proportional.  Note that 20/7 times 7 is 20 (the numerator of the 20/40), and that 20/7 times 14 is 40.  The constant of proportionality is thus 20/7.

Carly takes three steps to walk the same distance as jim walks in four steps. each of carly’s steps covers 0. 5 metres. how many
myrzilka [38]

The distance travelled by Jim in 24 step is 9 miles by unitary method.

According to the given question.

The number of steps travelled by Jim = 24

Also, it is given that "Carly takes three steps to walk the same distance as Jim walks in four steps".

Therefore, by unitary mehod we can say that

The number of steps walked by Carly = 3 × (24/4) = 3 × 6  = 18

So, the distance travelled by Carly in 18 steps

= 18 × 0.5miles

= 9 miles

Since, the Carly's 18 steps is equals to Jim's 24 steps.

Therefore, the distance travelled by Jim in 24 step is 9 miles.
