Answer:
Option: c is correct.
Step-by-step explanation:
We are given that paco needs at least 3/8 yard of twine to build a model ship.
that is we require twine of amount greater than 3/8 yards.
<em>now we need to check among the given options which quantity is greater than 3/8 yards.</em>
a)
3/10 yard.
As we know that for two rational numbers with the same numerator but with different denominator the number whose denominator is smaller is a greater quantity.
Hence 3/10 < 3/8
Hence option a is incorrect.
b)
1/4 yard
As to compare to rational numbers we have to either make the numerator equal or their denominator equal. Hence here we multiply and divide 1/4 by 2 to get 8 in the denominator.

as 2/8 < 3/8
since the denominator is same and the number with the same denominator but with different numerator are compared as whose numerator is greater is a greater quantity.
Hence option b is incorrect.
c)
3/4 yard
Clearly both the numbers have the same numerator but different denominator and we know that for two rational numbers with the same numerator but with different denominator the number whose denominator is smaller is a greater quantity.
Hence 3/8 < 3/4
Hence, option c is correct.
d)
1/8 yard
clearly both the numbers have the same denominator and we know that for two rational numbers withe same denominator but with different numerator the number whose numerator is smaller is a smaller quantity.
Hence, 1/8 < 3/8
Hence, option d is incorrect.
Answer:
The answer to your question is Brand B
Step-by-step explanation:
Data
Brand A amount of 20 pencils cost $6
Brand B amount of 40 pencils cost $8.5
Process
1.- Calculate the unit price of each brand of pencils dividing the cost by the number of pencils
Brand A 6/20 = $0.3
Brand B 8.5/40 = $0.21
2.- Conclusion
Brand B is a better deal because you buy more pencils for a lower price.
Answer:
x = (22/17), y= (79/17)
Step-by-step explanation:
Just substitute x = 2y - 8 into y = 9x - 7 and solve.
20 imperial gallons = 90.9218 litres
so i'd say you'd need to buy 91 bottles or...
20 US Liquid gallons = 75.7082 litres
so you'd have to buy 76 bottles.
Hope this answers your question! It depends what gallon you're working from.
