-1/4 will be ration because all fractions are rational
Answer with explanation:
x=the number of boxes containing red pens and
y = the number of boxes containing blue pens.
The expression which describes the number of red pen and blue pen in Boxes is
= (12 x-10)+(10 y-5)
The equivalent expression are
1.By Adding like terms
=12 x +1 0 y -10 -5
=12 x +1 0 y -15
or Using Associative Property of addition of three numbers which is
⇒a+(b+c)=(a+b)+c=(a+c)+b
= 10 y +12 x -15
or
= -15 +10 y +12 x
or
= 12 x -15 +10 y
1 I 4 6 -3
I 4 10
---------------------
4 10 7
the remainder is 7.
