Select the smallest fraction from the following fractions.
2/4, 3/6, 1,3, 7/9

1/3

Step-by-step explanation:

2/4 and 3/6 can be simplified to 1/2.

1/3 is smaller than 1/2 because it have a larger denominator, but the same numerator.

Multiple 1/3 by 3/3 and you get 3/9, which is smaller than 7/9.  

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.
