Question

Sara had 7/8 pounds of turkey. She used 2/3 pound for sandwiches. How many pounds of turkey does Sara have left?

Answer 1

Make the denominators the same.
\[\frac{ 7 }{ 8 }\times \frac{ 3 }{ 3 }\] Then: \[\frac{ 2 }{ 3 }\times \frac{ 8 }{ 8 }\] Can you multiply those fractions and tell me what you get for each?

Answer 2

not really. im not completely understanding why you would put 8 over 8 and 3 over 3

Answer 3

Oh because we wanna get the denominators to be the same, in order to subtract the fractions.

Answer 4

so........ \[21 \over 24\] and \[16 \over 24\] ?

Answer 5

Yes, now subtract.

Answer 6

\[5 \over 24?\]

Answer 7

Yes. That's your answer.
