Multiplying numerators and denominators to get the LCD in all fraction denominators\[ = \frac{-1 \times 2}{8 \times 2} - \frac{1}{16} - \frac{3 \times 2}{8 \times 2} + \frac{5 \times 2}{8 \times 2} \]Then rewriting the equation with the equivalent fractions\[ = \frac{-2}{16} - \frac{1}{16} - \frac{6}{16} + \frac{10}{16} \]With like denominators Think "4 plus 5 is 9, plus 10 is 19" Another Example: 14 + 12. Break into Tens and Units: 10 + 4 + 10 + 2. Add the Units: 4 + 2 = 6. Now add on the Tens: 6 + 10 + 10 = 26. Aim for Ten. nYGXYJqN2pQ. When a number is close to ten we can "borrow" from the other number so it reaches ten. qc2Q.
