Answer 2

Answer:

a) 7/30 b) 16/33

Step-by-step explanation:

a)   $\frac{7}{10} - \frac{7}{15} = \frac{7*3}{10 *3} - \frac{7*2} {15*2}= \frac{21}{30} - \frac{14}{30} = \frac{21-14}{30}= \frac{7}{30}$

   We can make the denominators the same by multiplying both denominator and numerator with same number and and the other fraction too. Then we can directly subtract the numerators with the same denominator. Hence the answer.

b) $\frac{8}{3}$  ÷  $\frac{11}{2}$ = $\frac{8}{3} * \frac{2}{11} = \frac{8*2}{3*11} = \frac{16}{33}$

  Division of any two fractions means we want to take the reciprocal of the right hand side fraction and then we want to take the multiplication of the two.

Why we doing these all, you will understand at higher classes.

Reciprocal of   $\frac{x}{y} = \frac{y}{x}$ , which means you want to change the numerator to denominator and vice versa.

' * ' means multiplication.
