Answer 2

$\huge \mathbb \red{QUESTION:}$

What do you add to 15/4 to make 4?

$\huge \mathbb \red{ANSWER : }$

r={1/4} (decimal: .25)

PREMISES

15/4+r=4

CALCULATIONS

The sum “15/4 plus an addend to make 4” can be written algebraically as:

15/4+r=4

15/4–15/4+r=4–15/4

0+r=4–3 3/4

r=4–3–3/4

r=1–3/4

r=

1/4 (decimal: .25)

PROOF

If r=1/4, then the equations

15/4+r=4

15/4+1/4=4

16/4=4 and

4=4 establish the root (zero) r=1/4 of the sum 15/4+r=4
