Answer:
D1= 60 HOSTS
network address - 200.120.80.64/26
subnet mask -255.255.255.192/26
D2 = 90 HOSTS
network address - 200.120.80.0/25
subnet mask -255.255.255.128/25
D3 = 90 HOSTS
network address - 200.120.80.128/25
subnet mask -255.255.255.128/25

The binary number system is also referred as base-2 numeral system. The numeric values in the binary system are represented with only two symbols "0" and "1". The base 10 number system on the other hand is the usual number system that uses decimal numbers.
In the binary system the number to the left of the point
is a whole number and every number further left gets 2
times bigger. The first digit on the right means halves and every number further right is 2 times smaller.
In the base 10 system number greater than 1 appear to the left of a decimal point. Values that
are a fraction appear to the right of the decimal point. Every number further left is 10 times bigger, and right 10 times smaller.
