Question

Estimate the length of blue and green sticks if the length of the red stick is 1 foot and the length of the brown stick is 4 inches.

• A. Green stick: 7 inches; Blue Stick: 10 inches
• B. Green stick: 10 inches; Blue Stick: 6 inches
• C. Green stick: 2 inches; Blue Stick: 12 inches
• D. Green stick: 3 inches; Blue Stick: 5 inches

Answer 1

The correct option is A Green stick: 7 inches; Blue Stick: 10 inches

$\text{Say:}$
The length of red stick = 1 foot
The length of brown stick = 4 inches

$\text{Steps:}$
$\bullet$ We know, 1 foot = 12 inches

$\bullet$ The length of red stick = 12 inches

$\bullet$ The green stick is a little longer than the brown stick and around half the length of the red stick.

$\bullet$ So, the estimated length of the green stick will be around half of 12 inches. So, the estimated length of the green stick is around 6 inches.

$\bullet$ The blue stick is a little shorter than the red stick and longer than the green stick. So, the estimated length of the blue stick will be more than 6 inches but less than 12 inches.

$\bullet$ Hence, the option with the length of the green stick around 6 inches and the length of the blue stick between 6 inches and 12 inches is option B.
