Answer 1

Jupiter is around 1/10 of the sun and 1.02m is around 1/10 of 10m.
I think your issue is that most pocket adding machines can't deal with 10 figure numbers like 0.0000000072
Earth is around 1/100 of the sun so expect around 0.1m
Trap have a go at doing the total in km not meters so duplicate by 0.0000072 then change over in your mind by expelling 3 naughts ot zeros or simply drop the kilo from kilometer and there you are
EX Earth is 12756 km X 0,0000072 = 0.0918 km partition by 1000 = 0.0918 m
Check earth is around 1/100 sun measurements so anticipate that the answer will be around 0.1 meters or 10 cm so that works.
to entirety up just 5 zeros after the decimal point and you have it.

Answer 2

Diameters in meters:

Sun 1,391,000,000 m
Mercury 4,879,000 m
Venus 12,104,000 m
Earth 12,756,000 m
Mars 6,794,000 m
Jupiter 142,984,000 m
Saturn 120,526,000 m
Uranus 51,118,000 m
Neptune 49,528,000 m

Ratio:
`(10)/(1,391,000,000) =7.2* 10^(-9)`
Multiply each planet by
`7.2* 10^(-9)` to get the diameter in meters.

Mercury 4,879,000 m ×
`7.2* 10^(-9)` = 0.035704 m = 37.7 mm
and so on...
