Hi :) Complex fractions is a new subject for me, so I'd appreciate it if you could help me out with an explanation on how to get the answers. Thank you! Also, there are actually 8 questions, but I didn't want to burden you with too many of them, so I'll make a part two ^^

1. 10/8/9 ?/? ÷ ?/? → ?/? ÷ ?/? → ?/? ÷ (simplify) ?/? → ?/?
2. 5 7/5 ?/? ÷ ?/? → ?/? ÷ ?/? → ?/? ÷ (simplify) ?/? → ?/?
3. 2/5/4 ?/? ÷ ?/? → ?/? ÷ ?/? → ?/? ÷ (simplify) ?/? → ?/?

*if you don't understand this or if you don't know the answers, please don't answer, I genuinely need help*

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
