Question

Which expression has the sum of 11/12

Answer 1

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) $\dfrac{1}{12}+ \dfrac{5}{12} + \dfrac{5}{12}$

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

So;

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

$= \dfrac{11}{12}$

b)

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

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

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

$=\dfrac{11}{4}$

c)

$\dfrac{5}{6}+\dfrac{6}{6}$

$=\dfrac{5+6}{6}$

$=\dfrac{11}{6}$

d)

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

$=\dfrac{10+2}{12}$

$= \dfrac{12}{12}$

= 1

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