5. Which of the following shows 12/28 written in prime factored form to help in reducing the fraction to simplest form?
A. 7x2x2/3x2x2
B. 6x2/4x4
C. 377
D. 3x2x2/

 A. _3x2x2

              7x2x2

Step-by-step explanation:

given fraction 12/28

here is the numerator = 12 = 2x2x3

here is the Denominator = 28 = 2x2x7

the prime factorization  simplest form  is _12_= _2x2x3

                                                                        28           7x2x2

the simplest form is 12/28 is 3/7

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
