45.5 degrees would be the most precise, since it has 3 significant figures. All the other values have only 2 significant figures, including 980 (the final zero is NOT significant), or 1 significant figure (30 degrees).
Expressed in figures, this is equal to 7,500,000,000.

There are 1609.344 metres in one mile. Therefore, rounded to three significant figures, 75 metres is equal to 75/1609.344 = 0.0466 miles.
It is common practice to round to the item with the lowest number of significant figures in a math problem. 48 + 27 = 75 All of the items have two significant digits, therefore the answer stays 75.
The density is 75 g/54 cm^3 = 1.4 g/cm^3, rounded to two significant figures.

To find 75 percent of a value, multiply the value by 0.75. In this instance, 0.75 x 1378 = 1033.5. Don't forget to round the value to two significant figures, thus: $1033.50.
1.2 * 102 (scientific notation, two significant figures)120 (rounded off to two significant figures)120.7008 (seven significant figures)The ratio between kilometers and miles is 1mile=1,604 kilometers / 1 kilometer=0,6234 miles (aproximated). To make it simple if you want to convert miles in kilometers just multiply your distance in miles by 1,6. If you want to convert kilometers in miles just dived your distance in kilometers by 1,6. This will not give you the exact value but it will be very close. 75miles=120,3kilometers
Kph is km/h and mph is mi/h. 1 mi = 1.61km.75 km/h x 1mi/1.61km = 47 mi/h or 47 mph (rounded to two significant figures due to 75 kph).
Expressed in figures, this is equal to 7,500,000,000.
There are 25.4 millimetres in one inch. Therefore, rounded to two decimal places, 75 millimetres is equal to 75/25.4 = 2.95 inches.
