--description--

Given a photo size in megabytes (MB), and hard drive capacity in gigabytes (GB), return the number of photos the hard drive can store using the following constraints:

• 1 gigabyte equals 1000 megabytes.
• Return the number of whole photos the drive can store.

--hints--

number_of_photos(1, 1) should return 1000.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(number_of_photos(1, 1), 1000)`)
}})

number_of_photos(2, 1) should return 500.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(number_of_photos(2, 1), 500)`)
}})

number_of_photos(4, 256) should return 64000.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(number_of_photos(4, 256), 64000)`)
}})

number_of_photos(3.5, 750) should return 214285.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(number_of_photos(3.5, 750), 214285)`)
}})

number_of_photos(3.5, 5.5) should return 1571.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(number_of_photos(3.5, 5.5), 1571)`)
}})
