Answer 1

given facts: 4/15 of the wall was painted by Owen and 8/15 of the same wall was painted by Olan
what is asked: what total fraction of the wall is painted
what operation: addition
number sentence: 4/15 + 8/15 = 12/15
answer: 12/15 of the wall is painted

Answer 2

Given facts:
Owen painted 4/15 of the wall, and Olan painted 8/15 of the wall.

Problem asked:
How much of the wall is painted?

Operation used:
Becuase Owen and Olan painted the same wall, addition will be used to find out how much of the wall is painted.

Number sentence:
A number sentence is an equation that is expressed with numbers and operative symbols. The following equation is your number sentence:


`(4)/(15) + (8)/(15)`

Answer:
Both fractions have the same denominator, so you can add the numerators together:


`(4)/(15) + (8)/(15) = (12)/(15)`

We can simplify this answer by finding the greatest common factor (GCF) of the numerator and denominator.

Factors of 12: {1,2,3,4,6,12}
Factors of 15: {1,3,5,15}

Divide the numerator and denominator by the GCF:


`(12)/(15) / (3)/(3) = (4)/(5)`

4/5 of the wall is painted.
