Answer 1

Answer:

1. A factor of a number is an exact divisor of given number.

2.All co-primes need not be both prime numbers.

3.If the number is divisible by 2 and 3 is also divisible by 4 and 6.

4. 30 kg : 60 kg = 3 m : 6m.

5.5) 20% of 80 + 30% of 90 =43.

6.Convert into cm: 12 m 25 cm=1,200cm 25cm.

7.A fraction is a number representing a part of whole.

8.To add or subtract the unlike fractions, convert them into like fractions.

9. 0 is neither prime nor composite number.

10.The Least common factor {LCM} of two or more numbers is the smallest of their common multiples.​
