Question

Mr. Girson is exactly 6.25 feet tall. His daughter is half his height. Which equation would provide the best estimate of how many feet taller Mr. Girson is than his daughter?

6 – 6 ÷ 2 = 3
6 + 6 ÷ 2 = 9
6 – 1/2 – 6 = 1/2
6 + 1/2 + 6 = 12 1/2

Answer 1

Answer:

A

Step-by-step explanation:

None of them really. But the first one is the expected answer. The question is a good one because it involves estimation. He is approximately 6 feet.

His daughter is 6/2 = 3. You divide by 2 because she is 1/2 his height.

The first equation tells you that he is 3 feet taller than his daughter. It should be written as

6 - (6÷2) = ?

6 - 3 = 3 which is A

Answer 2

Answer:

6 – 6 ÷ 2 = 3

Step-by-step explanation:

Mr. G is 6.25 ft tall

Daughter G is 1/2 his height

Daughter = 1/2 (6.25)

           

We want to find how much taller Mr G is than his daughter

Take Mr G height and subtract his daughters

6.25 - 1/2 (6.25)

The question asks for an estimate, so we can round 6.25 to 6

6 - 1/2 (6) = 3
