What is the answer to 5 12 multiplied by 1 512?

Answer 1

There are two possible interpretations of your question:

1) It is two fractions: 5/12 × 1/512 = (5×1)/(12×512) = 5/6144

2) It is two mixed numbers with the solidus between the numerator denominator of the fractional parts being stripped: 5 1/2 × 1 5/12

When working with mixed numbers, it is usually easier to convert them to improper fractions, do the operations, and then to convert any resulting improper fraction back to a mixed number:

5 1/2 × 1 5/12 = (5×2+1)/2 × (1×12+5)/12

= 11/2 × 17/12

= (11×17)/(2×12)

= 187/24

= (7×24+19)/24

= 7 19/24

(In future it would be useful to use the word "over" instead of the solidus (/) as the solidus will be deleted without replacement.)

Answer 2

It is 5/6144.
