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.

What is the answer to this problem 9e+10 =
mihalych1998 [28]
E=1 because you would subtract 9 from both sides since it's on the side with the variable. The nines would cancel eachother out so you would have e on the left side then 10-9=1 so it would be e=1
