Question

(4-¹—5-¹)÷3-¹ simplify​

Answer 1

Step-by-step explanation:

${4}^{ - 1} - {5}^{ - 1 } \div {3}^{ - 1} = \frac{1}{4} - \frac{1}{5} \div \frac{1}{3}$

$= \frac{5 - 4}{20} \div \frac{1}{3} = \frac{1}{20} \div \frac{1}{3}$

(LCM = 20)

$\frac{1}{20} \times 3 = \frac{3}{20}$ (when dividing fraction number the RHS side to the division will become reciprocal)
