First find the slope using
(y2-y1)/(x2-x1)
(1-2)/(3-1)=-1/2
Since only one answer has s slope of -1/2 the answer is B
1. 8/9 ÷ 4/9 is done by inverting the divisor (4/9) and then multiplying:
(8/9)(9/4) = 8/4 = 2 (answer)
2. 1/3 ÷ 6 is done similarly: (1/3)(1/6) = 1/18 (answer)
3. 4 ÷ 1/5 = 4 * 5 = 20 (answer)
4. 7 1/2 ÷ 1/4 = (15/2)(4/1) = 30 (answer)
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)
