Hi friends! Could you help me? "Use the least common denominator to write an equivalent fraction for each fraction."

5 4
__ __
9' 15

1\5

Step-by-step explanation:

lcm of 9 and 15 = 45

5/45 + 4/45

= 9/45

= 1/5

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.

is it 35
