To convert meters to kilometers, use the conversion factor: . Thus, .
Calculation:
.
The problem provides multiple-choice answers, and the correct answer is expressed as a fraction, so express as a fraction:
after simplification.
Therefore, the solution to the problem is km.
\( 291cm^2=?m^2 \)
Because kilometers are larger units than meters! Since 1 km = 1000 m, you need fewer kilometers to represent the same distance. Think of it like trading 1000 pennies for 1 dollar.
Write 0.125 as , then simplify! Divide both numerator and denominator by their greatest common factor (125):
12500km is way too big - that's like saying a football field is longer than the distance across a country! 1.25km means the answer got bigger, which doesn't make sense when converting to larger units.
Yes! Remember "kilo" means 1000. So 1 kilometer = 1000 meters. When going from small to large units, you always get a smaller number. When going from large to small units, you get a bigger number.
The multiple choice answers include fractions, so the problem wants you to recognize that 0.125 = . Both forms are correct, but matching the answer format is important!
