1) .625x = 40, divide by .625 and x=64
so the recprical (and correct answer) is 1/64.
2) 6000/.24 = 25,000 is the population.
3) Since 2, 3, 5, and 7 are all prime numbers and have to common factors, the smallest possible multiple is the product of the numbers: 2x3x5x7= 210

Hello
1. 62.5%x40 = 25 so 1/25 is the reciprocal
2. 24%x = 6000 so x = 6000/24% = 25000
3. 2*3*5*7= 210
Hope This Helps!!
