can anyone help me

OpenStudy (anonymous):

Sure, first you got to tell us what you want help with.

OpenStudy (anonymous):

James added 3 and two-thirds plus 4 and one-eighth. His work is shown here. What did James do right? What did he do wrong? What should he have done? three and two-thirds plus 4 and one-eighth equals 7 and three-elevenths

OpenStudy (anonymous):

\[3\frac{ 2 }{ 3 } + 4\frac{ 1 }{ 8 } = 7\frac{ 3 }{ 11 }\] Is that the correct equation?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

Okay now let me think for a second. I want to see if I can figure it out. Its been awhile sense I was in 7th or 6th forgot what one I did it in.

OpenStudy (anonymous):

lol it is in 6th grade

OpenStudy (anonymous):

\[3\frac{ 2 }{ 3 } + 4\frac{ 1 }{ 8 } = 7\frac{ 3 }{ 11 }\] Here is what he did wrong. On the three-elevenths you cannot add the bottom. Like 8 + 3. You have to do what you did on the top with the bottom.

OpenStudy (anonymous):

ohh oka ty so much i am gonna become your fan

OpenStudy (anonymous):

Find what they go into, then times the top what they went into.

OpenStudy (anonymous):

Alright, next time you need help come to me. And your in connections right?

OpenStudy (anonymous):

i have no idea i am new at this

OpenStudy (anonymous):

Alright.

OpenStudy (anonymous):

hey can you answer this other question

OpenStudy (anonymous):

Maybe.

OpenStudy (anonymous):

lol ok Estimate 8 and one-third times 2 and four-fifths using any method you like. Then find the actual product. Use your estimate to show that your answer is reasonable.

OpenStudy (anonymous):

Okay, this is easy. I will walk you through it so you can know it for the next time.

OpenStudy (anonymous):

oka

OpenStudy (anonymous):

\[8\frac{ 1 }{ 3 } \times 2\frac{ 4 }{ 5 } = \]

OpenStudy (anonymous):

23.3

OpenStudy (anonymous):

what do you mean 23.3

OpenStudy (anonymous):

that is what 8 one third times 2 four fiths = now, round 23.3 down to 23.

OpenStudy (anonymous):

oka

OpenStudy (anonymous):

Hmm one sec trying to get the factor.

OpenStudy (anonymous):

oka

OpenStudy (anonymous):

this is the only factors I can find 2 times 11.5 = 23.

OpenStudy (anonymous):

I think that is correct but it might not be.

OpenStudy (anonymous):

oka so if your teacher wants you to put a full summry of that answer what would you put

OpenStudy (anonymous):

What do you mean a summary?

OpenStudy (anonymous):

Okay let me see. I think I know what you mean.

OpenStudy (anonymous):

well the question is Estimate 8 and one-third times 2 and four-fifths using any method you like. Then find the actual product. Use your estimate to show that your answer is reasonable. and she said explain it

OpenStudy (anonymous):

but how like if you had a question like that what would you put

OpenStudy (anonymous):

\[8\frac{ 1 }{ 3 } \times 2 \frac{ 4 }{ 5 } = 23.3\] \[11.5 \times 2 = 23.3\] Fiirst get the answer to the equation. Then what you want to do is find what will go in to the number. Like times into the whole number. The number that times into the number is the factor.

OpenStudy (anonymous):

Make sure to make it your own words please. If it is connections academy, they search around for any signs of cheating.

OpenStudy (anonymous):

yea i know ty so much

OpenStudy (anonymous):

oka well ty so much and good night

OpenStudy (anonymous):

Yep good night.
