Kira and Mitch are each assigned a paper for a class they share. Kira decides to write 6 pages at a time while Mitch decides to write 9 pages at a time. If they end up writing the same number of pages, what is the smallest number of pages that the papers could have had?
The smallest number of pages the papers could have is 18.
Is there an error in the work shown below? If yes, identify the error and fix it.
Error is in Step 4 to Step 5. Student should have subtracted 3 from 97 before adding. The order of operation says to add and subtract from left to right.
Student A stated that the factored expression for 81+36 is 9(9+36), where a is the GCF of 81 and 36. Is this true or false? If false, find the correctly factored expression.
GCF of 81 and 36 is 9. But the student did not factor the 9 out of 36. The correct factored expression should be 9(9+4).
What is the missing base for the given power?
(_)^3=343
The blank is 7.
(7)^3=7*7*7=343
Spot a fix the error in the prime factorization below:
90
2*45
3*15
90= 2*3*15
15 is NOT Prime
15=3*5
90=2*3*3*5
Emily is looking for the GCF of 3 and 7. She claims that the GCF must be 21 since both 3 and 7 are factors of 21. State her error, then state the correct GF of 3 and 7.
21 is the LCM of 3 and 7.
The GCF of 3 and 7 is one since both values are prime.
Is there an error in the work shown below? If yes, identify the error and fix it.
Student made a mistake fromStep 2 to Step 3. Student should still have included parentheses around 64 - 6. The order of operation says to perform all operations inside parentheses and brackets first.
Student A stated that the factored expression for 48+64 is 4(12+16), where a is the GCF of 48 and 64. Is this true or false? If false, find the correctly factored expression.
This is false. 4 is not the GCF of 48 and 64.
The correction expression should be
16(3+4)
