A nail weighs about 1/10 oz. many nails are in a 5-lb box?
it’s 80 right
oops I mean how
Convert 5lbs to ounces. 5*16=80
If a nail weighs 1/10 of an ounce than there are 10 nails to an ounce.
So 80*10=800. Their are 800 nails in a 5 pound box.
To find out how many nails are in a 5-lb box, we need to calculate the number of nails based on their weight. Given that a nail weighs about 1/10 oz, we can use the concept of proportions to solve this problem.
Step 1: Convert 5 lbs to ounces.
Since there are 16 ounces in a pound, we multiply 5 by 16 to get:
5 lbs * 16 oz/lb = 80 oz
Step 2: Calculate the number of nails.
If one nail weighs 1/10 oz, we can set up a proportion to find the number of nails in 80 oz:
1 nail / (1/10 oz) = N nails / 80 oz
To cross multiply, we multiply the numerator of one fraction by the denominator of the other fraction:
1 * 80 = (1/10) * N
Simplifying the equation:
80 = N/10
Multiply both sides of the equation by 10 to isolate N:
80 * 10 = N
800 = N
Therefore, there are 800 nails in a 5-lb box.
1 lb. = 16 oz.
(5 * 16) / 1/10 = ?
