Answer these 2 questions and you get 15 points

Question 1: Option B:

Question 2: Option C:

Solution:

Question 1:

Given ratio is .

To find the equivalent ratio of .

10 and 14 have the common factor 2.

So divide both numerator and denominator by the common factor 2.

Hence option B is the correct answer.

Question 2:

Given ratio is .

To find the equivalent ratio of .

12 and 18 have the common factor 3.

So divide both numerator and denominator by the common factor 3.

Hence option C is the correct answer.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
