The land on Earth’s surface is represented by the seven continents. Europe has 77% of the dry land

while Africa has 20%. North America has 4/25 and Antarctica has 1/10 of the dry land. What fractional amount of the dry land is contained within the three remaining continents, combined?
A 13/30
B 27/100
C 32/235
D Not here

.77 + .2 + .16 + .1 = more than 100%

You have a typo
I doubt if Europe has 77%
