1. 15 / 1/3
When dividing, the second fraction flips over .
15* 3/1= 45/1= 45
2. 24 / 1/6
24*6= 144
4. 7/12 / 1/3
7/12*3/1
Cross out 3 and 12, divide by 3
12/3= 4
3/3= 1
7/4* 1/1. Multiply the numerator together. Multiply the denominators together.
7*1= 7
4*1= 4
7/4 or 1 3/4

Step-by-step explanation:
Answer: (B) The price elasticity of demand for good Z = 0.86
Step-by-step explanation:
The formula for determining elasticity of demand by using the midpoint method is
(Q2 - Q1)/[(Q2 + Q1)/2] / (P2 - P1)/[(P2 + P1)/2]
Where
P1 is the initial price of the item.
P2 is the final price of the item.
Q1 is the initial quantity demanded for the item.
Q2 is the final quantity demanded for the item.
From the information given,
P1 = 10
P2 = 15
Q1 = 85
Q2 = 60
The price elasticity of demand for good Z = (60 - 85)/[(60 + 85)/2] / (15 - 10)/[(15 + 10)/2]
= (-25/72.5) / (5/12.5) = -25/72.5 × 12.5/5
= - 312.5/362.5 = - 0.86
I think the answer is a = 4.5
81 ÷ 6 ÷ 3 = 4.5
I hope this helps, have a wonderful day!
