Answer 2

Answer:

ans is 0.13

Step-by-step explanation:

[13/4÷{5/4-1/2(5/2-1/4-1/6)}]

=[13/4÷{5×2-4×1/4×2(5×4-1×2/2×4-1/6)}]

=[13/4÷{6/8(18/8-1/6)}]

(dividing 6/8 &18/8 by 2)

=[13/4÷{3/4(9/4-1/6)}]

=[13/4÷{3/4(9×6-4×1/4×6)}]

=[13/4÷{3/4(50/24)}]

(dividing 50/24 by 2)

=[13/4÷{3/4(25/12)}]

=[13/4{3×25/4×12}]

=13/4÷75/48

=3.25/1.5625

=325/100÷15625/10000

(divide 325 by 100 & 15625 by 10000)

=13/4÷25/16

=52÷400

=0.13
