I need to know what goes in each box.<br> :)<br> 20 points
BartSMP [9]

Answer:

3/12 = 4/12

or

3/12 = 1/3

being are last boxes to autofill.

Step-by-step explanation:

1/12 +1/4 = 1/12 + 3/12 = 4.12 = 1/3

When adding the rule of fractions is where required make all denominators the same by dividing the one you want to change to- by the subset one you are changing.

12 / 4 = 3

we get 3/12

Then when adding same denominators 1/12 + 3/12 we just add the top values. = 4/12

The last box would be 4/12 but if asked to simplify we would automatically enter 1/3 for simplification.

As 4/12 = 1/3

Sergeeva-Olga [200]
$728.00 I’m assuming. Because the equation should be A(t)= P(1+i) ^t right? Telling us that P= principal, i= interest & t= time.
I’m assuming from MY financial mathematics class.
