**Question 1.

The Museum of Science and Industry in Chicago is about 11.600 meters from The Art Institute of Chicago. How many kilometers apart are the two buildings?

Answer:

Number of kilometers apart are the two buildings = 11.6.

Explanation:

Number of meters The Museum of Science and Industry in Chicago from The Art Institute of Chicago = 11.600.

Conversion:

1 kilometer = 1000 meters.

Number of kilometers apart are the two buildings = Number of meters The Museum of Science and Industry in Chicago from The Art Institute of Chicago ÷ 1000

= 11600 ÷ 1000

= 11.6.

Question 2.

Ms. Lee is 1.7 meters tall. Her daughter is 1.2 meters tall. How much taller is Ms. Lee in centimeters?

Answer:

50 centimeters taller is Ms. Lee than her daughter.

Explanation:

Number of meters tall Ms. Lee = 1.7.

Number of meters tall her daughter = 1.2.

Difference:

Number of meters is Ms. Lee – Number of meters is her daughter

= 1.7 – 1.2

= 0.5.

Conversion:

1 meters = 100 centimeters

=> 0.5 m = 100 × 0.5

=> 50 centimeters.

Question 3.

Doreen wants to put a model boat in a box. The model measures 252 mm tall and 459 mm wide. Can the model fit within a box that measures 28 cm tall and 32 cm wide? How do you know?

Answer:

Yes, the model fits within a box that measures 28 cm tall and 32 cm wide because Length of the box and Width of the box are more than the model.

Explanation:

Length of model = 252 mm.

Width of model = 459 mm.

Length of the box = 28 cm.

Width of the box = 32 cm.

Conversion:

1 cm = 100 mm.

=> Length of the box = 100 × 28 = 2800 mm.

=> Width of the box = 100 × 32 = 3200 mm.

Question 4.

An adult blue whale is 25.74 meters long. How long is the blue whale in centimeters?

Answer:

2574 cm is the blue whale in centimeters.

Explanation:

Length of an adult blue whale = 25.74 meters.

Conversion:

1 m = 100 cm.

=> 25.74 m = 100 × 25.74

= 2574 cm.

Question 5.

Ahmad and Eva are practicing for a bike race. Ahmad rode 3.4 km in one day. Eva rode 4.8 km the same day. How much farther did Eva ride in meters?

Answer:

1400 m farther Eva ride in meters.

Explanation:

Number of kilometers Ahmad rode the bike in one day = 3.4.

Number of kilometers Eva rode the bike the same day = 4.8.

Difference:

Number of kilometers Eva rode the bike the same day – Number of kilometers Ahmad rode the bike in one day

= 4.8 – 3.4.

= 1.4.

Conversion:

1 km = 1000 m.

=> 1.4 km = 1000 × 1.4

= 1400 m.

Question 6.

Steven has three crabapple trees in his yard. The height of one measures 610 cm. The second measures 760 cm and the third measures 910 cm. What is the sum of the heights of the trees in meters?

Answer:

22.8 m is the sum of the heights of the trees in meters.

Explanation:

Height of one measures = 610 cm.

Height of second measures = 760 cm.

Height of third measures = 910 cm.

Total height of three crabapple trees = Height of one measures + Height of second measures + Height of third measures

= 610 cm+ 760 cm + 910 cm

= 1370 cm + 910 cm

= 2280 cm.

Conversion:

1 m = 100 cm.

=> 2280 cm = 2280 ÷ 100

=> 22.8 m.
