SIMPLIFY 7/10+1/4-1/5=

Strike441 [17]

Answer:

3/4

Step-by-step explanation:

Q = $\frac{7}{10} +\frac{1}{4} -\frac{1}{5}$

{the smallest common multiple of 10, 4 and 5 is 5×2×2 = 20 (denominator)}

Q = $\frac{7×2}{10×2} +\frac{1×5}{4×5} -\frac{1×4}{5×4}$

= $\frac{14}{20} +\frac{5}{20} -\frac{4}{20}$

= $\frac{14+5-4}{20}$

= $\frac{15}{20}$

= $\frac{3×5}{4×5}$

= $\frac{3}{4}$
