Ming used the calculations shown to find out how much he would spend on 6 pounds of ground beef if 10 pounds of ground beef cost $25.00. StartFraction 10 pounds over 25 dollars EndFraction = StartFraction 10 pounds divided by 25 over 25 dollars divided by 25 EndFraction = StartFraction 0.4 over 1 EndFraction. Unit Price = 40 cents. 40 cents times 6 = 2 dollars and 40 cents. What was Ming's error? He determined pounds per dollar by dividing 10 by 25 but wrote the unit rate as a dollar value. He divided the numerator and the denominator of the fraction by 25. He made a mistake when finding the quotient of 10 pounds and 25 dollars. He made a mistake when finding the product of $0.40 and 6.

Answer:

He determined pounds per dollar by dividing 10 by 25 but wrote the unit rate as a dollar value.

Step-by-step explanation:

Given

[tex]\frac{10\ pounds}{\$25} = \frac{10\ pounds}{25} / \frac{\$25}{25} = \frac{0.4}{1}[/tex]

[tex]Unit\ Price = 40\ cents[/tex]

[tex]40\ cents * 6 = \$2.40[/tex]

Required

Determine Ming's error

Ming's error is from here

[tex]\frac{10\ pounds}{\$25} = \frac{10\ pounds}{25} / \frac{\$25}{25} = \frac{0.4}{1}[/tex]

He calculated the unit rate as pound per dollar.

So, after calculating the unit rate, the unit should be:

[tex]Unit\ Rate = 0.4\ pound/\$[/tex]

But instead, he solved as:

[tex]Unit\ Rate = \$0.4/ pound[/tex]

Hence, (a) is correct
