Question

The akashi kaikyo bridge in japan is about 1 4/9 times as long as the golden gate bridge in san francisco.The golden gate bridge is about 9,000 feet long. About how long is the akashi kaikyo

Answer 1

Answer: $13,000\ feet\ long$

Step-by-step explanation:

Let be "a" the lenght (in feet) of the Akashi Kaikyo Bridge in Japan  and "g" the lenght  (in feet) of the Golden Gate Bridge in San Francisco.

We can covert from mixed number to improper fraction by multplying the whole number part by the denominator of the fraction and adding this product to the numerator:

$1\frac{4}{9}=\frac{(1*9)+4}{9}=\frac{13}{9}$

Then, according to the information provided in the exercise:, we can write this equation:

 $a=\frac{13}{9}g$

Knowing that:

$g=9,000$

We can substitute this value into $a=\frac{13}{9}g$ to find "a". Then we get:

$a=\frac{13}{9}(9,000)=13,000$
