Which expression has the sum of 11/12.

A. 1/12+5/12+5/12

B. 5/4+3/4+3/4

C. 5/6+6/6

D. 10/12+2/12

Answer:

A. 1/12+5/12+5/12

Step-by-step explanation:

From the given options; let us calculate the fractions and see which one tallies with 11/12

a) $\frac{1}{12}+\frac{5}{12}+\frac{5}{12}$

The lowest common multiple (L.C.M) here is 12 because 12 goes in all the denominators.

So;

= $\frac{1+5+5}{12}$

= $\frac{11}{12}$

$\frac{5}{4}+\frac{3}{4}+\frac{3}{4}$

Here, the lowest number that can be divisible by the denominators is 4

= $\frac{5+3+3}{4}$

= $\frac{11}{4}$

$\frac{5}{6}+\frac{6}{6}$ $\frac{5+6}{6}$ $\frac{11}{6}$

$\frac{10}{12}+\frac{2}{12}$ $\frac{10+2}{12}$ $\frac{12}{12}$

= 1

Thus, from the given options, the expression that has the sum of 11/12 is option A.
