Brian places baseball cards in an album with 9 on each page. he could represent the total number of baseball cards he has in an album using the expression 9t. brian is thinking about putting an additional 7 cards on each page. which expression would represent the number of baseball cards in the album now?

16t

Step-by-step explanation:

Since you can deduce that t represents pages and when there are 9 cards per page then the expression is 9t. If you add 7 cards per page, then there will be 16 cards a page. Then, the expression is 16t

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
