Answer 2

7 billions * 0.5

Answer 3

3.5 billion hectares

Answer 4

^

It would give the answer in hectares, you have to convert it to acres afterward

Answer 5

1 acre = 0.4047 hectares

Answer 6

so if 1 ha = 2.47 acres would i divide 2.47 by 3.5 billion

Answer 7

1acre^2 = 0.1638 ha
u have to square the raito

Answer 8

so 1 ha = 6.1 acres^2
7 billions * 6.1 acres^2 ( or * 2.47 if you need only acres)

Answer 9

well i have to have it in unit conversion using 1ha=2.47 acres

Answer 10

ok, so its 7 billions * 2.47

Answer 11

but only one person needs .5 ha for food so wouldn't i divide some where
