How do get a percentage?
If a child weighs 20 Kg and his father weighs 80kg what is the percentage of the child's weight COMPARED to his Father's? ANSWER. Divide the small amount ,by the large amount, then MULTIPLY your result by 100. OR move the decimal point 2 places to the right. 20/80 equals 1/4 X 100 equals 25 per cent.You get a percentage by multiplying the decimal fraction by 100. For example, 1.00= 100%, .25=25%, .33=33%, 2.33=233%. If it is a fraction, first change the fraction to a decimal and multiply by 100. Examples are 3/4=.75=75%, 3/10=.30=30%, 45/100=.45=45%/you divide your given number by the total, for example, you have 3 apples, but you had 10, you divide 3 by 10, and you get .30 which equals 30%first you get the number you want the percentage of e.g 250then you divide that by 100then you multiply the answer by the amount of percentage you are looking for e.g 30%250 divide by 100 multiply by 30 = 75 ...simple :D
What is the mass of a runner moving at the speed of 2.5 msec with a momentum of 200 kg m per sec?
Momentum is defined as mass * velocity, M=m*v. Momentum: 200kg*m/sec velocity: 2.5m/sec mass: (200kg*m/sec) / (2.5m/sec) = 80kg If remembering equations like these is difficult, then something useful for you would be to understand the concept of dimensional analysis. That is a fancy word for looking at the units of the given quantities. If you know that mass is kilograms, then you can figure out how to manipulate the units m/sec and kg*m/sec in order to come out with a final unit of kg. By dividing kg*m/sec with m/sec you end up getting (kg*m*sec) / (m*sec), leaving just kg left which is the unit you were looking for. Therefore you should divide 200 by 2.5 for a final answer of 80kg.

No. "g" is grams and "kg" is kilogram. There are 1000g in every kg, so 80kg is 80,000g and 80g is just 0.008kg
How much does a 80kg person weigh?
To calculate weight of a known mass, the following formula is used:W = m⋅gThus, to calculate the weight of a 80kg person:W = (80kg)*(9.81 m/s^2)W = 784.8 kg⋅m⋅s^2 = 784.8N
