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: OPTION B

Explanation:

Let's make the conversions:

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

`(11\ grams)((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)((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)((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)((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.

Answer 2

B.

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
