There are 10 centiseconds in a decisecond
So
There are 2.1 deciseconds in 210 centiseconds
There are 100 centiseconds in one second. Therefore, 157 centiseconds is equal to 157/100 = 1.57 seconds.
There are 100 centiseconds in one second. Therefore, 3.5 seconds is equal to 3.5 x 100 = 350 centiseconds.
100
Divide by 6000 centiseconds per minute.
210 ÷ 7 = 30
210 ÷ 7 = 30
210 times.
210 milligrams is .210 grams.
