Multiply it by 100 to express it as a percentage
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 50 are: 1, 2, 5, 10, 25, 50 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100 The factors of 3050 are: 1, 2, 5, 10, 25, 50, 61, 122, 305, 610, 1525, 3050
3050 1 raised to any power is just 1, so 3050 * 1 = 3050
It is: MMML = 3050
There are 100 centimetres in one metre. Therefore, 30.5 metres is equal to 30.5 x 100 = 3050 centimetres.
4 quarters = 1 dollar so 3050 quarters = 3050/4 = 762.5 dollars
There are 1000 metres in one kilometre. Therefore, 3050 metres is equal to 3050/1000 = 3.05 kilometres.
