Find the value of a

- $\frac {1}{7} - \frac {5}{16 } = a $
- $\frac {3}{13} - a =\frac { 20}{143}$
- $ a - \frac {1}{11 } = \frac {29}{165}$
- $\frac {1}{3} - \frac {5}{13 } = a $
- $\frac {5}{18} \times \frac {1}{4 } =a$
- $\frac {5}{19} \times a =\frac { 5}{209}$
- $a \times \frac {1}{5 } = \frac {1}{7}$

Solution

Evaluate below expression

- $\frac {1}{19} \times \frac {2}{9 }$
- $\frac {2}{19} - \frac {1}{10 } $
- $\frac {4}{13} \times \frac {1}{11 } $
- $ \frac { 3}{76} \div \frac {3}{8 } $
- $\frac {2}{9} - \frac {5}{11 } = $
- $\frac {4}{13} \times \frac {5}{16 } - \frac {5}{52}$
- $\frac {1}{3} \times \frac {5}{11 } + \frac {5}{33}$
- $\frac {1}{16} \times \frac {2}{19 } \div \frac { 1}{152}$
- $\frac {1}{18} \times \frac {1}{5 } - \frac {1}{90}$
- $\frac {3}{11} \times \frac {1}{9 } $
- $\frac {1}{4} - \frac {1}{3 } - \frac {-1}{12}$
- $\frac {4}{7} - \frac {4}{11 } + \frac {16}{77}$
- $\frac {1}{19} - \frac {1}{15 } - \frac {-4}{285}$

Solution

Find the additive inverse of each of the following:

- $\frac {1}{2}$
- $\frac {-2}{7}$
- $ \frac {-1}{11}$
- 12
- $\frac {-3}{10}$

- Every rational number has a reciprocal
- 3/2 lies between 1 and 2
- The negative of 1 is 1 itself.
- For all rational numbers a and b, a – b = b – a.
- -1/2 is smaller than -2

Solution

Find the multiplicative inverse of the following.

- $ \frac {-12}{11}$
- $ \frac {-1}{9}$
- $ \frac {2}{3}$
- $\frac {-1}{2} \times \frac {-2}{5}$
- $\frac {-1}{8} \times \frac {-8}{7}$
- -11
