a. Convert 18 centimeters to inches


b. Convert 240 kilograms to pounds


c. Convert 13 miles to feet.


d. Convert 18 ounces to grams


e. Convert 234 grams to kilograms

Answer 1

PART a)

a. Convert 18 centimeters to inches

As we know that

1 inch = 2.54 cm

now we have

`18 cm = 18 cm * (1 inch)/(2.54 cm)`

`18 cm = 7.09 inch`

b. Convert 240 kilograms to pounds

As we know that

1 pound = 0.454 kg

now we have

`240 kg = 240 kg * (1 pound)/(0.454 kg)`

`240 kg = 528.6 pound`

c. Convert 13 miles to feet.

As we know that

1 mile = 5280 feet

now we have

`13 miles = 13 miles * (5280 feet)/(1 mile)`

`13 miles = 68640 feet`

d. Convert 18 ounces to grams

As we know that

1 ounce = 28.35 g

now we have

`18 ounce = 18 ounce * (28.35 g)/(1 ounce)`

`18 ounce = 510.3 g`

e. Convert 234 grams to kilograms

As we know that

1 kg = 1000 g

now we have

`234 gram = 234 grams * (1 kg)/(1000 g)`

`234 gram = 0.234 kg`

Answer 2

Hello!

The answers are:

a. 7.09 inches

b. 528.63 pounds

c. 64,480 feets

d. 510.3 g

e. 0.234 kg

Why?

Let's apply the following conversions:

`1in=2.54cm[tex]</p><p>[tex]1pound=0.454kg`

`1mile=5280ft`

`1ounce=28.35g`

`1kg=1000g`

So,

a.

`8cm*(1inch)/(2.54cm)=7.09inch`

b.

`240kg*(1pound)/(0.454kg)=528.63pounds`

c.

`13miles*(5280ft)/(1mile)=68640ft`

d.

`18ounces*(28.35g)/(1ounce)=510.3g`

e.

`234g*(1kg)/(1000g)=0.234kg`

Have a nice day!
