7/5+3/10/6/11-1/22

Question

dont get it. / means they are fractions.

Answer 1

I assume the expression is written as

 

[(7/5) + (3/10)] / [(6/11) - (1/22)]

 

 

Lets work with fractions in the first bracket.

 

(7/5) + (3/10)

 

We cannot add our subtract fractions with different denominators.  We need to find the lowest common denominator (LCD).  The LCD is 10.

 

(14 / 10) + (3/10) = 17 / 10

 

 

We do the same thing to the second bracket.

 

(6/11) - (1/22)

 

The LCD is 22.

 

(12 / 22) - (1 / 22) = 11 / 22 = 1 / 11

 

 

Now, divide the two results.

 

(17 / 10) / (1 / 11) =

 

(17 / 10)(11) =

 

187 / 10 =

 

18.7
