Question

Which shows a correct comparison? A. 11 grams = 1,000 milligrams B. 7 liters > 700 milliliters C. 5 milliliters > 5 liters D. 4 kilograms < 3,000 grams

Answer 1

Answer:

B.

Step-by-step explanation:

Unit prefix:

mili = 0.001

kilo = 1,000

A. 11 grams = 11 · 1,000 miligrams = 11,000 miligrams ≠ 1,000 miligrams

B. 7 liters = 7 · 1,000 mililiters = 7,000 mililiters > 700 mililiters  CORRECT :)

C. 5 mililiters < 5 liters = 5,000 mililiters

D. 4 kilograms = 4 · 1,000 grams = 4,000 grams > 3,000 grams

Answer 2

Answer: OPTION B

Step-by-step explanation:

Let's make the conversions:

A. 11 grams to milligrams (Remember that 1 gram= 1,000 milligrams):

$(11\ grams)(\frac{1,000\ milligrams}{1\ gram})=11,000\ milligrams$

The $11\ grams=11,000\ milligrams$

B. 7 liters to milliliters (Remember that 1 liter= 1,000 milliliters):

$(7\ liters)(\frac{1,000\ milliliters}{1\ liter})=7,000\ milliters$

Then:

$7,000\ milliters>700 milliliters$ or $7\ liters>700 milliliters$

C. 5 milliliters to liters:

$(5\ milliliters)(\frac{1\ liter}{1,000\ milliliters})=0.005\ liters$

Then:

$0.005\ liters<5 liters$ or $5\ milliliters<5 liters$

D. 4 kilograms to grams (Remember that 1 kilogram= 1,000 grams):

$(4\ kilograms)(\frac{1,000\ grams}{1\ kilogram})=4,000\ grams$

Then:

$4,000\ grams>3,000\ grams$ or  $4\ kilograms>3,000\ grams$

Therefore, the option that shows the correct comparisson is the option B.
