7 nails have a mass of 50 g.How many nails have a mass of 1/2 a kg please?
Use a proportion the way I showed you for the last problem. I'll be glad to check your work.

7 nails have a mass of 50g. How many nails have a mass of 1/2
kg
i do not know you tell me#
To find out how many nails have a mass of 1/2 a kg, we need to compare the masses of the nails given in the question.
Given:
7 nails = 50 g
To compare this with 1/2 a kg, we need to convert 1/2 a kg to grams.
Since 1 kg is equal to 1000 g,
1/2 a kg = 1/2 x 1000 g = 500 g
Now we can set up a proportion to find the number of nails with a mass of 1/2 a kg.
Proportion:
7 nails / 50 g = x nails / 500 g
To solve for x, we can cross multiply:
7 nails * 500 g = 50 g * x nails
3500 g = 50 g * x nails
Finally, we can solve for x by dividing both sides of the equation by 50 g:
x nails = 3500 g / 50 g
x nails = 70
Therefore, there are 70 nails with a mass of 1/2 a kg.
