Question

• Represent -5/8 and 7/8
on the number line.
• Find four rational number between 1/5 and 1/3.
• Solve using property:
$\frac{ -6}{8} + \frac{ -5}{6} + \frac{ -4}{9} + \frac{ -15}{7}$
• Solve using property:
$\frac{2}{5} \times( \frac{ -3}{7}) - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}$
• Name the property used in each of the following.
$\frac{ -7}{11} \times \frac{ -3}{5} = \frac{ - 3}{5} \times \frac{7}{11}$
$- \frac{2}{3} \times( \frac{3}{4} + \frac{1}{2} ) = ( \frac{ - 2}{3} \times \frac{3}{4} ) + ( \frac{ - 2}{3} \times \frac{ - 1}{ 2}$
$\frac{1}{3} + ( \frac{4}{9} + ( \frac{ - 4}{3} )) = ( \frac{1}{3} + \frac{4}{9} ) + ( \frac{ - 4}{3} )$
$\frac{ - 2}{7} + 0 = 0 + \frac{ - 2}{7} = - \frac{2}{7}$
$\frac{3}{8} \times 1 = 1 \times \frac{3}{8} = \frac{3}{8}$
• Find the multiplicative inverse of:
(a)
$- 1 \times \frac{1}{8}$
(b)
$3 \times \frac{1}{3}$
• Find the additive inverse of:
(a)
$- 3$
(b)
$\frac{4}{ - 7}$
•Using distributive law, find the square of 101.
• Find a pythogorean triplet in which one member is 12.
• Express 169 as the sum of 11 odd numbers
• How many numbers lie between squares of 65 and 66.
