Question

Nasir is 5 feet tall. Which of the following is closest to Nasir's height, in

centimeters? (1 foot-30.48 centimeters)
a. 60 centimeters
b. 84 centimeters
c. 128 centimeters
d. 152 centimeters

Answer 1

I did the quiz and picked D and got it right

Answer 2

152 centimeters (D)

Explanation:

1 foot is 30.48 centimeters

5 feet is 5 groups of 30.48

So, we could write this as

30.48 + 30.48 + 30.48 + 30.48 + 30.48,

or, in a simpler way:

30.48 x 5

(multiplication is repeated addition. x5 means that there are 5 groups of that value. if there is x1 that means that there is only 1 group (1 foot), and x2 means that there are 2 "groups" (2 feet) )

30.48 x 5 = 152.4

Nasir's height is about 152.4 centimeters, which is closest to the answer choice of 152 (D).
