Answer 9

` Which ratio correctly compares 10 m to 50 cm? `
First you would need to convert 10 meters to centimeters.
(Provided that 1m=100cm)

\(\large\color{black}{ 10~{\rm m} \times\frac{\LARGE 100~{\rm cm}}{\LARGE 1 {\rm m}} ~~~ \Rightarrow~~~ 10~{\rm \cancel{m}} \times\frac{\LARGE 100~{\rm cm}}{\LARGE 1 {\rm \cancel{m}}} ~~~ \Rightarrow~~~ 1000~{\rm cm} }\)

So now we can re-write the question as:
` Which ratio correctly compares 1000cm to 50 cm? `
\(\large\color{black}{ 1000~{\rm cm}:50~{\rm cm} }\)
\(\large\color{black}{ 1000:50 }\)
\(\large\color{black}{ 100:5 }\)

ANSWER: \(\large\color{black}{ 20:1 }\)

*please

Answer 15

you basically need to convert all the units of length to the same unit. I would suggest to convert 15 meters to centimeters, and not 45cm to meters
(even though meter is the SI unit)
