c) True

Composite numbers are those numbers which have more than 2 factors. Factors of 91 are 1 , 7 , 13 and 91. So, it is a composite number.

d) False

It is not important that if a number is divisible by 25, then it will also be divisible by 3.

e) True

HCF of 26 and 27 is 1.

f) True

Factor of a number cannot be greater than the number.

g) True

Decimal fractions have multiples of ten as denominators.

h) True

Decimal numbers are fractional number.

i) False

There is 1 decimal place in 63.9.
