A teacher wants to give 3 markers to each of her 25 students. Markers come
in packages of 8. How many packages of
markers will the teacher need?

Answers

Answer 1
Answer: First, find out how many markers in total the teacher will need. 
25*3=75
Then, find out how many packages the teacher will need by dividing by 8 because that's how many are in each package.
(75)/(8)=9.375
Now because there is a remainder of .375 that tells us that there are not enough markers in 9 packages to give all students 3 each.

She will have to buy an additional package to give every student 3 markers each. 

10 Packages are needed.
Answer 2
Answer: Teacher wants to give 3 markers to each of 25 students. To find how much markes she need we have to multiply 3*25, so 3*25=75

Finally we can find how many packages she need. To get the answer we have to divide 75 by 8, so
75:8=9.375
Now we have to round up because we cant buy 9.3 packages. The final result its 10.

Do u need a common denominator if you have adding and dividing in fractions?

Answers

You only need a common denominator for adding and subtracting! 
No you don't because you use the reciprocal and then multiply to divide the fractions, not a common denominator, you need that when there are different denominators and you are adding/subtracting

42 less than the product of 28 and an unknown number is 154

Answers

42 less than (-42) the product of (multiply) 28 (28) and an unknown number (x) is (=) 154
28 times x-24=154
pemdas
multiplication
28 times x=28x
28x-42=154
add 42 to both sides
28x+42-42=154+42
28x=196
divide both sides by 28
x=7
the number is 7
28X-42=154
+42 +42
-----------------
28X = 196
------ -----
28 28
X = 7
