Question

3/13+10/13+(-7/5)+(-3/5)​

Answer 1

Answer:

Least common multiple (LCM) of 15 and 12 = 5 × 3 × 4 = 60

= (11 × 4)/(15 × 4) – (7 × 3)/(20 × 3)

[Converting each fraction to an equivalent fraction with denominator 60]

= 44/60 – 21/60

= (44 – 21)/60

= 23/60

3. Simplify: 4⁵/₆ – 2³/₈ + 3⁷/₁₂

Solution:

4⁵/₆ – 2³/₈ + 3⁷/₁₂

= (6 × 4 + 5)/6 – (2 × 8 + 3)/8 + (3 × 12 + 7)/12

= 29/6 – 19/8 + 43/12

= 29/6 – 19/8 + 43/12
