Answer 1

`(1)/(5)`

• 1.2 is the same as:
• 12 ÷ 10
• =
  `(12)/(10)`
• dividing by 6 is the same as
• 
  `(1)/(6)`
• 1.2 ÷ 6
• =
  `(12)/(10)` ×
  `(1)/(6)`
• we can times the tops and bottoms together
• =
  `(12)/(60)`
• We can simplify this
• For example, the top and bottom are both even numbers
• =
  `(6)/(30)`
• We can simplify again by dividing by 2
• =
  `(3)/(15)`
• We can simplify again by dividing by 3
