We have 11 ounces plus 29 ounces

plus 5 pounds is equal to how many pounds,

or blank pounds? So we need to add these three

quantities right here, and they want us to give the

answer in pounds. And we can only add quantities

that have the same units. So let’s just add these ounces

first, just to get them out of the way. And then we could see, maybe we

can convert them to pounds, or convert the pounds

to ounces. We’ll probably convert them to

pounds, so that our final answer is in pounds. So if we just add 11

ounces plus 29 ounces, what do we get? Well, 11 plus 29 is 40. Let me write it like this. This right here is 40 ounces. So we need to add 40 ounces to

5 pounds to get a certain number of pounds. So let’s convert this right here

to pounds, and then, once we have that in pounds, we can

just add it to that, and then we’ll have our final answer. So 40 ounces, we want to

convert it to pounds. So we need to multiply it by

something where, in the units, we have ounces in the

denominator, and we have pounds in the numerator. And we need that so that these

ounces cancel out with these ounces, and we’re just

left with pounds. And we know already that there

are 16 ounces per pound. So there are 16 ounces

per 1 pound. Or you could say there’s 1 pound

per every 16 ounces. Or you could say there’s 1/16

of a pound per ounce. Either way, if you multiply

these two quantities, the ounces cancel out. And this whole quantity becomes,

when you multiply it out, you’re left with

40 divided by 16. 40/16. It’s really 40 times 1

over 16, but the 1 doesn’t change anything. And then 40/16 pounds. And let’s see if we can write

this as a mixed number, or if we can simplify this

a little bit. Both of these numbers

are divisible by 8. So let’s divide them

both by 8. If you divide 40 by

8, you get 5. You divide 16 by 8, you get 2. So it’s 5/2. If we want to write this as a

mixed number– or even better, let’s write it as a decimal. This is 5 divided by 2. 2 goes into 5 2 times. 2 times 2 is 4. Subtract. You have a remainder, 1. We want a decimal, so let’s put

the decimal right there and keep bringing down 0’s. So let’s bring down

a 0 right there. 2 goes into 10 5 times. 5 times 2 is 10. And we have no remainder. So this is exactly 2.5,

which makes sense. 5 over 2 is the same thing as

2 and 1/2 as a mixed number, which is the exact same

thing as 2.5. This first part right here

simplified down to 5/2 pounds, or 2.5 pounds. So the problem becomes 2.5

pounds plus 5 pounds. And 2.5 plus 5, fairly

straightforward, it’s 7.5. So this is equal

to 7.5 pounds. 7.5 pounds is our answer,

and we’re done.

I don't know if this is because i'm an asian student

these stuffs are extremely easy for me

@zeroin1330 I guess grammar certainly doesn't come extremely easy to you, does it.

@zeroin1330 LOL, This stuff is easy if it is taught well. What grade are you in?

@mike3177

you're right indeed.

could you point out my grammatical mistakes?

thank you friend 🙂
