- How many inches are there in 750,000,000 feet?(11 votes)
- Well, it's quite simple.

just time the feet number by 12 times.

The simple answer is:

F (Feet) = 750,000,000

F X 12 (How many inches go into a foot) = A (Answer)

A very simple way to find out your answer is:

75 X 12 = 70 X 10 = 700 + 5 X 2 = 10

700 + 10 = 710 ( + 7 0's)

= 710 0000000

= 7,100,000,000 Inches(11 votes)

- how do you divide fractions(5 votes)
- Invert the second fraction, then multiply across:

(1/2)÷(3/5) becomes (1/2)*(5/3), and multiplying across gives us (5/6)(6 votes)

- what happens if you have 2/3 yards how do you counvert it to inches?(4 votes)
- You have to break the problem down into steps.

You might start with the question: How many feet are in a yard? The answer is three, so the next question is what is 2/3 of three feet? The answer is two feet.

I'll leave the rest to you. If there are 12 inches in a foot, how many inches in two feet?(6 votes)

- How to convert feet to inches(2 votes)
- Remember that a foot is equal to twelve inches.

So if I had two feet of string, I would multiply twelve inches by two (measurement of string) and that would give me twenty-four inches of string converted from 2 feet.(2 votes)

- 18th equals how many inches(1 vote)
- how to convert small units into big unitsss(1 vote)
- Think about it in reverse. If you have 24 inches, you have 2x12 inches = 1 foot. If you have 36 inches, you have 3x12 inches = 1 foot. It gets harder when you have 'in-between numbers' such as 40 inches. 40 inches/12 = 3 with remainder of 4. So you have 3 feet, 4 inches or 3 4/12 feet = 3 1/3 feet.(1 vote)

- If 4.5 feet is 4 feet and 6 inches then is 4.8 feet 4 feet and 9 inches? Do you always +1 to the inches?(1 vote)
- What is the difference between a foot and an inch?(1 vote)
- 1/2 hour equals How much day(1 vote)
- Do you mean, how many minutes are in half an hour? Well, if there are 60 minutes in 1 hour, then cutting that in half would give you 30 minutes. So basically 60 divided by 2. 60/2= 30

If you mean, how many 1/2 hours are in a day, then you would take how many hours are in a day (24) and multiply by 2 (the number of 1/2 hour segments in an hour). So it would be 24 multiplied by 2. 24x2=48.(1 vote)

- How many yards in two miles?(1 vote)
- 1 mile is 1,760 yards. You can multiply 1,760 and 2 or add 1,760 and 1,760. You will get the answer of

3,520 yards.(1 vote)

## Video transcript

Complete the table to show
equivalent measurements in feet and inches. So they gave us the
measurements in feet, and they want us to
figure out how many inches this number of feet are. So we know that 1 foot is
equivalent to 12 inches, so we can fill out this
first one right over here. 12 inches make up 1 foot. 1 foot is 12 inches. Now, what about 2 feet? Well, that's just going
to be 2 times 12 inches. 12 inches per foot times
2 feet gives us 24 inches. Well, here I have 5 feet. I have 12 feet--
here I have 5 feet. I have 12 inches per foot,
so 5 times 12 is 60 inches. And then finally, 10 feet. 10 feet times 12 inches per
foot gets us to 120 inches.
