Question

Find ten rational numbers between minus 2 by 5 and 1 by 2​

Answer 1

-2/5 & 1/2

Finding LCM of 5 & 2

LCM = 10

-2×2 / 5×2. &. 1×5 / 2×5

=> -4/10 & 5/10

MULTIPLYING BOTH BY 2

-8/10 & 10/20

SO RATIONAL NOS. BETWEEN -8/20 & 10/20 WILL BE

-7/20, -6/20, -5/20, -4/20, -3/20, -2/20, -1/20, 0/20, 1/20, 2/20, 3/20, 4/20 ••••••

Answer 2

Answer:

$- \frac{2}{5} = - \frac{2 \times 2}{5 \times 2} = - \frac{4}{10} \\ \frac{1}{2} = \frac{1 \times 5}{2 \times 5} = \frac{5}{10} \\ again \\ - \frac{4}{10} = - \frac{4 \times 11}{10 \times 11} = - \frac{44}{110} \\ \frac{5}{10} = \frac{5 \times 11}{10 \times 11} = \frac{55}{110} \\ ten \: rational \: numbers \: between \\ \: - \frac{2}{5} and \: \frac{1}{2} are - \frac{41}{110} - \frac{39}{110} \\ - \frac{31}{110} - \frac{23}{110} - \frac{19}{110} \frac{7}{110} \frac{17}{110} \\ \frac{21}{110} \frac{31}{110} \frac{51}{110}$
