Answer 1

Answer:

a) 4/7×3/5÷16/21 of 49/7×3/7

Always use the BODMAS rule here

Border , Of , Division , Multiply , Addition , Subtraction

=> 4/7×3/5÷(16/21×49/4) × 3/7

=> 4/7×3/5÷(28/3)×3/7

=> 4/7×(3/5×3/28)×3/7

=> 4/7×(9/140)×3/7

$= > \frac{4 \times 3 \times9 }{7 \times 140 \times 7} \\ = > \frac{108}{6860}$

b)

$4 \frac{5}{15} \div \frac{21}{26} \times \frac{35}{57} \\ = > \frac{65}{15} \div \frac{21}{26} \times \frac{35}{57} \\ = > ( \frac{65}{15} \times \frac{26}{21}) \times \frac{35}{57} \\ = > \frac{1690}{315} \times \frac{35}{57} \\ = > \frac{1690}{513}$
