right i don't get what u wrote at first EXP jst means times ten. I hope u can multiply by ten especially decimals (jst move the decimal to the right by one). 1cm=10mm hence 160 cm =1600mm jst multiply by 10
1km=1000m 14km= 14000 m
1kg=1000g hence 109g=0.109
do u see what i am doing? when multiplying by 100 we add 2 zeros to the end if it's a whole number, if it's a decimal we move the decimal two places along 0.12 become 12 and 12 becomes 1200. When u deal with 1000000 u move the decimal by 6 places or add 6 zeros to a whole number.
also centi means 1/100 so centi metre means 1/100 of a metere
mili means 1/1000 and kilo means 1000 times. 1/100 means move decimal point to the left two spaces assuming whole numbers have a decimal point at the end of them ie 24 (24.0) becomes 0.24 and 49989 becomes 49.989
so we have 1km=1000m so 250m is 0.25km
1g=1000mg so 2000mg= 2g
1L=1000L so 5L=5000 ml
ill leave the last one to do urself if 1cm=10mm how much is 16 cm?
(think for a bit---I have included the answer right at the bottom :) )

Check out the links. The second one is great. 16 oz = 453.59 g 2 qt = 1.8922 L 5 mi = 8.0472 75mL = L I'll let you calculate this yourself. 1 L = 1000 mL A decometer is (electronics) An adding-type phasemeter which rotates continuously and adds up the total number of degrees of phase shift between two signals, such as those received from two transmitters in the Decca navigation system. Perhaps you want decimeter. A metric unit of length equal to one-tenth (10-1) of a meter. In other words, there are 10 centimeters to one decimeter. Centi means "hundredth" and deci means "tenth"

ok don't worry scientific notation isn't hard... all you have to do is divide the number by 10*___ where the blank is the number of times you have to move the decimal to reach a number less than 10. then when you write it after it write the number less than 10 * 10 to the blank ( the one we used before) power.
the answers to the conversions are
14km= 14000 m
109 g= .109 kg
250m= .250 km

always multiply it by 10. so:
160 cm = 1600 mm = 1.6 x 10 to the third power
14 km = 140 m = 1.4 x 10 to the second power
and so on. the exponent is always the amount of numbers in the number, not including the first number.

scientific notation is used when you need to make numbers with lots of zeros look smaller. for example 500,000,000,000,000 = 5 x 10^14. The ^ means to the power of like exponents. in exponents you multiply a number by itself the number of times it shows in the corner. they typically look like this:
160cm = 1600mm
14km = 1400m
109g = 0.109kg
250m = 0.25km
2000mg = 2g
5L= 5000 mL
16cm = 160mm

the one that will most be affected is mean.
bar graph exists on an x and y axis, where y generally measures how high something is, like your grades on tests for example.
x axis could represent test 1, test 2, test 3, etc....
