2/3 of a pound of walnuts costs $2.50
would this be right
0.8 cent per pound
unit price
when 2/3 of a pound costs $2.50
you are saying that 1 pounds costs less than a penny???
really???
if 2/3 pounds costs 2.50
then 1 pound costs 2.5/(2/3) = $3.75
0.6667x = 2.50
x = 2.50 / 0.6667
x - 3.7498 = $3.75 per pound
To find the unit price (price per pound), you need to divide the total cost by the weight.
In this case, 2/3 of a pound of walnuts costs $2.50. Therefore, the unit price would be:
Unit price = Total cost / Weight
Unit price = $2.50 / (2/3) pounds
To divide by a fraction, you can multiply by its reciprocal:
Unit price = $2.50 * (3/2) / 1
Unit price = $3.75 / 1
Unit price = $3.75
So the unit price for walnuts in this case is $3.75 per pound, not 0.8 cent per pound.
To determine the unit price, or cost per pound, you can divide the total cost by the total weight.
In this case, you have 2/3 of a pound of walnuts that costs $2.50. To find the unit price, divide $2.50 by 2/3 pound:
Unit price = $2.50 / (2/3) pound
To divide by a fraction, you can multiply by the reciprocal of the fraction. Reciprocating means swapping the numerator and the denominator. Therefore:
Unit price = $2.50 * (3/2) pound
When multiplying fractions, you can multiply the numerators together and the denominators together:
Unit price = $2.50 * 3 / 2
Multiply the whole numbers and then divide by the denominator:
Unit price = $7.50 / 2
Finally, divide $7.50 by 2:
Unit price = $3.75
So, the unit price for walnuts is $3.75 per pound, not 0.8 cents as you stated.
