What do the fractions 10/16; 15/24; 20/32; 25/40; and 30/48 have in common?

The Highest Common Factor is 8

Step-by-step explanation:

This is called ' Highest Common Factor'

Considering the denominators which are 16, 24, 32, 40 and 48

16 = 2×2×2×2

24 = 2×2×2×3

32 = 2×2×2×2×2

40 = 2×2×2×5

48 = 2×2×2×2×3

What they have in common most is 2×2×2 = 8

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
