The answer is:
Example Question #145 : Numbers And Operations
Convert yards feet inches into inches.
Start by converting the yards into inches. Recall that there are feet in a yard, and inches in a foot.
Next, convert feet into inches.
Now add up all the inches.
Example Question #146 : Numbers And Operations
Convert hours minutes and seconds into seconds.
Start by converting the hours into seconds. Recall that there are minutes in an hour and seconds in a minute.
Thus, there are seconds in hours.

Example Question #11 : Units And Unit Conversions
You have 34oz of ground beef which you plan on making into hambrugers to grill with your friends. One of your friends is from Europe, and she is used to the metric system. She claims that burgers made with a of beef are the best. If you decide to make burgers of this size, how many can you make? Round to the nearest whole burger.
Note:
You have 34oz of ground beef which you plan on making into hambrugers to grill with your friends. One of your friends is from Europe, and she is used to the metric system. She claims that burgers made with a of beef are the best. If you decide to make burgers of this size, how many can you make? Round to the nearest whole burger.
Note:
Let's begin by running through what we need to do.
1) Convert 34 oz to pounds
2) Convert the answer to 2) to kilograms
3) Divide the answer to 3) by
Okay, to find the number of pounds we have, do the following:
1)
So, we have 2.125lbs of ground beef
2) Let's find what 2.125lbs is in kg
So, we have 0.966kg of beef.
3) Finally, let's see how many burgers we can make.
Now, we need to round to the nearest burger, so we can make about 4 burgers.
Example Question #16 : Units And Unit Conversions
If you need 256 inches of cloth, and the store from which you want to buy it only sells it in two-foot increments, how much will you have to buy?
One foot is equal to 12 inches, so divide 256 inches by the conversion factor 12 inches/foot to obtain the equivalent in feet:
.
The next highest even number of feet is 22 feet, the correct choice.
Example Question #142 : Numbers And Operations
A high school student runs one fourth of a mile in two minutes and thirty seconds. What is his average speed in miles per hour?
Use division to rewrite the runner's speed in terms of miles per minute. One fourth of a mile run in two minutes and thirty seconds can be restated as
miles per minute.
Divide the fractions by first rewriting the latter as an improper fraction:
Rewrite as a product of fractions by taking the reciprocal of the latter number:
Cross-cancel, then multiply across:
miles per minute.
Since 60 minutes make one hour, multiply by 60 minutes per hour:
Put the 60 over 1, cross-cancel, and multiply across:
The runner's speed is 6 miles per hour.
Example Question #21 : Units And Unit Conversions
Convert hours, minutes, and seconds into seconds.
Start by converting hours into seconds.
Next, convert minutes into seconds.
Now, add these seconds together along with the seconds given in the question.
