7 nails has a of 50g how many nails have a mass of 1/2kg

1 / 2 kg = 500 g

500 g / 50 g = 10

10 * 7 = 70 nails

Oh, I'd say about 14 nails. But let's just hope they're not too heavy for your fingers to handle!

To find the number of nails with a mass of 1/2 kg, we need to set up a proportion using the given information.

First, let's convert the mass of 1/2 kg to grams:
1 kg = 1000 g
1/2 kg = (1/2) * 1000 = 500 g

Now we can set up the proportion:
7 nails / 50g = x nails / 500g

To solve for x, we can cross-multiply and then divide:
7 * 500 = 50 * x
3500 = 50x

Divide both sides of the equation by 50:
3500/50 = x
70 = x

Therefore, there are 70 nails with a mass of 1/2 kg.

To find out how many nails have a mass of 1/2 kg, we can set up a proportion using the ratio of the number of nails to their mass.

Let's call the number of nails with a mass of 1/2 kg as "x". We can write the proportion as:

7 nails / 50g = x nails / (1/2 kg)

First, let's convert the mass of 50g to kilograms. Since 1 kg is equal to 1000 grams, we divide 50g by 1000 to get:

50g / 1000 = 0.05 kg

Now, we can rewrite the proportion:

7 / 0.05 = x / 0.5

To solve for "x", we can cross-multiply and then solve for "x":

7 * 0.5 = x * 0.05

3.5 = 0.05x

Divide both sides by 0.05:

3.5 / 0.05 = x

x = 70

Therefore, there are 70 nails that have a mass of 1/2 kg.
