Answer 1

Answer: 67.5 cm

Explanation:

Jason has 4 lengths of ropes

first is
`3\ in.\approx 7.5\ cm`

second is
`15\ cm`

Third is
`0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]`

fourth is
`0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]`

the total length of rope is the sum of four lengths

`\Rightarrow 7.5+15+30+15=67.5\ cm`
