1/5 + 1/3 x 1/4

According to the "Order of Operations" rules, multiplications or divisions  (from left to right) must be done before additions or subtractions (from left to right).

1/3 x 1/4 = 1/12   (Numerator = 1 x 1 = 1 and Denominator = 3 x 4 = 12)

Therefore, 1/5 + 1/3 x 1/4 = 1/5 + 1/12

Using common denominator,   1/5 + 1/12 = 12/60 + 5/60 = 17/60

Please let me know if you need any further explanation.

(1 / 5) + (((1 / 3) x 1) / 4) = 0.283333333

So do I

1/5+1/3 x 1/4

= 1/5 + 1/12

= [ 1 × 12 ] / [ 5 × 12] + [ 1 × 5 ] / [ 12 × 5 ] [ L.C.M of 5 & 12 is  5 × 12 = 60 ]

= 12/60 + 5/60 

= [ 12 + 5 ] / 60 [ Addition of numerator since the denominator is same]

= 17/60
