Question

The lowest recorded temperature in Peru was -13 2/5 and the highest recorded temp was 120 2/3 . What is the difference between the highest and lowest temperature

Answer 1

120 2/3 - (-13 2/5)

= 120 2/3 + 13 2/5

= (120+13) (2/3 + 2/5)

= 133 + (10/15 + 6/15)

= 133 + 16/15

= 133 + 1 1/15

= 134 1/15
