Answer 1

Answer:

hh

Step-by-step explanation:

1x 2x 3x = 0.002304. now you can do

Answer 2

Answer:

let first ratio = 1x

let second ratio = 2x

let third ratio = 3x

According to the question

$(1x {)}^{3} + (2x {)}^{3} + (3x {)}^{3} = 0.002304 \\ x {}^{3} + 8x {}^{3} + 27x {}^{3 } = 0.002304 \\ 36x {}^{3} = 0.002304 \\ x {}^{3} = \frac{2304}{1000000 \times 36} \\ x {}^{3 } = \frac{64}{1000000} \\ x = \sqrt[3]{ \frac{64}{1000000} } \\ x = \frac{4}{100} \\ x = 0.04$
