Question

Annalisa, Keiko, and Stefan want to compare their heights. Annalisa is 64 inches tall. Stefan tells her, "I'm about 7.5 centimeters taller than you." Keiko knows she is 1.5 inches shorter than Stefan. Give the heights of all three people in both inches and centimeters to the nearest half unit. Annalisa is 64 inches or about cm tall. Stefan is about inches or about cm tall. Keiko is about inches or about cm tall.

Answer 1

As 1 inch = 2.54 cm.

As Annalisa is 64 inches tall,

so the height of Annalisa in centimeter = 64 x 2.54 cm = 162.5 cm (approximately).

Stefen is about 7.5 centimeters taller than Annalisa,

So, height of Stefen in centimeter= 162.5+7.5=170 cm.

and the height of Stefen in inches = 170/ 2.54 cm= 67 inches (approximately).

Keiko is about 1.5 inches shorter than Stefen,

So, the height of Keiko in inches= 67-1.5=65.5 inches.

and the height of Keiko in centimeter = 71.5 x 2.54 cm= 166.5 cm (approximately).

Hence, Annalisa is 64 inches or about 162.5 cm tall.

Stefan is about 67 inches or about 170 cm tall.

Keiko is about 65.5 inches or about 166.5 cm tall.
