You start by cross multiplying:
9 x 8 = 72
This is considered the fraction on the left's value.
You do the same for the other side:
10 x 7 = 70
This is considered the value of the fraction 7/8
72 has a greater value than 70.
Therefore, 9/10 is larger.
Ok I can help you on number 5 and 6. Sorry I dont understand number 7. You are correct on number six. There is not enough information because they do not say how many are 12 and how many are younger than 12. So on number 5 you would take 67 and divide it by 5. That is 13.4 so your answer for number 5 would be 13.4. Hope this helps!
Answer:
x+5=12
x+7=15
x+ 1/2=1
x+1/3=1
4(x+1)= 8
1.5+x=3

Answer:
0.83
Step-by-step explanation:
If the price-elasticity of demand for chips is 0.75, then a 20 percent increase in price would result in a 15 percent decrease in the demand quantity.
As per the question statement, the price-elasticity of demand for chips is 0.75 and there is a 20 percent increase in price.
We are required to calculate the resulting decrease in the demand quantity by percent, based on the conditions mentioned in the statement above.
Here, given Price-Elasticity of Demand = 0.75
Also given the percent increase in price = 20
Now, we know that,
= [(Percentage change in quantity demanded)/(Percentage change in price]
Or, [0.75 = (x/20)]...[Assuming "Percentage change in quantity demanded" to be "x"]
Or, [x = (20 * 0.75)]
Or, [x = 15]
That is, If the price-elasticity of demand for chips is 0.75, then a 20 percent increase in price would result in a 15 percent decrease in the demand quantity.
- Price-Elasticity of Demand: Price Elasticity of Demand is a measurement of the change in the consumption of a product in relation to a change in its price and is expressed mathematically as the quotient of (Percentage Change in Quantity Demanded) divided by (Percentage Change in Price)
