*Make it a whole number.*

See the steps below :

*Make them a whole number by multiplying it with a power of 10. (both should be multiplied with the same number)*

1.

1.

1.2 × 10² = 120

1.02 × 10² = 102

*2.*Find the GCD of the two results.

120 = 2 × 2 × 2 × 3 ×5

102 = 2 × 3 × 17

Common Factors ⇒ 2¹ × 3¹

∴gcd ( 120,102 ) = 2 × 3 = 6

*3.*Multiply the GCD by the inverse of the power of ten the decimals were multiplied with.

6 × r ( 10² ) = 0.6

**Ans=0.6**
