Quinn and Alexander are painting their bedroom. Quinn has painted 2/5 of his room. Alexander has painted 2/3 of his room. Who ha

AleksAgata [21]

Answer:

Alexander

Step-by-step explanation:

Alexander has painted 2/3 of his room. Quinn has painted 2/5 of his. To find who has painted more, convert both fractions to have the same denominators. An easy way to do this is to multiply the numerator and denominator of one fraction by the denominator of the other, then do the same for the other fraction. So, $\frac{2}{3}$ · 5 = $\frac{10}{15}$ and $\frac{2}{5}$ · 3 = $\frac{6}{15}$ .

$\frac{10}{15}$ > $\frac{6}{15}$ . So, Alexander has painted more of his room than Quinn has.
