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:
[tex]\frac{4}{15} + \frac{8}{15}[/tex]
Answer:
Both fractions have the same denominator, so you can add the numerators together:
[tex]\frac{4}{15} + \frac{8}{15} = \frac{12}{15} [/tex]
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:
[tex]\frac{12}{15} \div \frac{3}{3} = \frac{4}{5}[/tex]
4/5 of the wall is painted.
