Answer:
4 kg of sugar would contain 
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
Solve for x. Cross multiply.
Divide both sides by 3
4 kg of sugar would contain crystals.

The person whose walk is longer is Erica.
Erica's walk is 8/9 times longer than Erica's walk.
<h3>Whose walks the longer distance?</h3>
In order to determine who walked the longer distance, we would convert the fractions to percentages.
3/4 becomes 75%
2/3 becomes 66.7%
Erica's percentage is smaller, thus, she walks a longer distance.
Jordan's walk is 8/9 times longer
(2/3 ÷3/4) (2/3 x 4/3 = 8/9)
