Hello!
For #1, the LCD is (A) 12 since both numbers go into 12 as their minimal number.
For #2, the missing number is (B) 4 because 1/4*4/4=4/16.
For #3, the answer is (B) 3 because you have to crossmultiply 20n(4*15) to find the answer.
for #4, the correct answer is (A) 4/5 is less than 5/6 because when converted into fractions with a common denominator, 24/30 is less than 25/30.
For #5, the LCD is 36; therefore, the answer is (A) because the fractions in the answer are properly converted to their new denominator.
I really hope I helped!
Answer:
$85
Step-by-step explanation:
To find the answer, we need to divide 1,615 by 19, since it says he earned 19 times the amount last year.
1,615/19=85
He only earned 85 dollars last year.
Hope this helps!
Marsh Trail is longer than Woodland trail by 2.5 miles
Step-by-step explanation:
A town park has 2 biking trails
1. Marsh Trail is 5 and three over ten miles long
2. Woodland trail is 2 and 4 over 5 miles long
We need to find that Marsh Trail is how much longer than
Woodland trail
To do that we will subtract the length of the Woodland trail from the
length of the Marsh Trail
∵ The length of Marsh Trail is 5 and three over ten miles
- 5 and three over ten = 
∵ 
= 0.3
∴ = 5.3 miles
∵ The length of Woodland trail is 2 and 4 over 5 miles
- 2 and 4 over 5 = 
∵ 
= 0.8
∴ = 2.8
∴ The difference = 5.3 - 2.8
∴ The difference = 2.5 miles
Marsh Trail is longer than Woodland trail by 2.5 miles

Answer: 9.2 years
Step-by-step explanation:
Given the following :
Mean(m) = 11.7 years
Standard deviation (s) = 1.2 years
Recall the z-score formula :
Z = (x - m) / s
We can find the z-score by locating the value of 2% in the negative z-table, then solve for x.
2% = 0.02
0.02 falls most closely to 0.02018whuch is under - 2.05.
Using the z-score value in the formula above :
-2.05 = (x - 11.7) / 1.2
Cross multiply
(-2.05 × 1.2) = x - 11.7
-2.46 = x - 11.7
x = - 2.46 + 11.7
x = 9.24 years
