Study Notes
Multiplication of Fractions
- (1 \frac{1}{2} \times \frac{3}{4} = \frac{9}{8} = 1 \frac{1}{8})
- (\frac{5}{2} \times \frac{1}{2} = \frac{5}{4} = 1 \frac{1}{4})
- (1 \frac{4}{7} \times 2 \frac{1}{3} = \frac{26}{7} = 3 \frac{5}{7})
Fractions of Quantity
- From 3/4 of an apple pie, Zoe will eat ( \frac{1}{6} \times \frac{3}{4} = \frac{1}{8} ) of the whole pie.
Area of Rectangles
- Area of a rectangle (length ( \frac{4}{5} ), width ( \frac{1}{3} )):
- ( \frac{4}{5} \times \frac{1}{3} = \frac{4}{15} ) sq. units
- Area of a rectangle (length ( \frac{7}{5} ), width ( \frac{1}{3} )):
- ( \frac{7}{5} \times \frac{1}{3} = \frac{7}{15} ) sq. units
Finding Missing Values
- ( \frac{1}{2} \times x = \frac{2}{10} )
- Solving gives ( x = \frac{2}{5} )
- ( \frac{3}{4} \times y = \frac{21}{32} )
- Solving gives ( y = \frac{7}{8} )
Common Fraction Applications
- Marteen plans to paint (\frac{2}{3}) of her room, intending to paint (\frac{1}{4}) of that before lunch:
- Total painted before lunch: ( \frac{1}{4} \times \frac{2}{3} = \frac{1}{6} )
Photo Resizing
- Reducing a photo’s size requires multiplying by a fraction less than one whole.
- Expanding a photo’s size requires multiplying by a fraction greater than one whole.
Bus Route Distance
- Gia's school bus route is (5 \frac{1}{2}) miles; the return route is (1 \frac{3}{5}) times longer:
- Length of the bus route home: (8 \frac{4}{5}) miles.
