To determine if ( \frac{21}{27} ) and ( \frac{35}{45} ) are proportional, we can simplify both fractions. ( \frac{21}{27} ) simplifies to ( \frac{7}{9} ), and ( \frac{35}{45} ) simplifies to ( \frac{7}{9} ) as well. Since both simplified fractions are equal, ( \frac{21}{27} ) and ( \frac{35}{45} ) are indeed proportional.
The LCM of 45 and 10 is 90
2/5 (divide both sides by 9)
The only number that goes into both 8 and 45 is 1
9
Both 9 and 3 go into both numbers. 45/54 = 5/6 45/54 = 15/18
