subtract 1 1/2 from the sum of 2 1/6 and 3 5/8

Question

its about fraction

Answer 1

First convert the mixed numbers to improper fractions.

 

1 1/2 = 3 / 2

 

2 1/6 = 13 / 6

 

3 5/8 = 29 / 8

 

 

"sum" means to add the terms.  'subtract" means to minus.

 

[(13 / 6) + (29 / 8)] - (3 / 2)

 

 

Get the lowest common denominators.

 

[(52 / 24)  + (87 / 24] - (36 / 24)

 

 

Now you can simplify the expression straight on using PEMDAS.  After simplifying, you can convert the answer to a mixed number.

Answer 2

subtract 1 1/2 from the sum of 2 1/6 and 3 5/8

 

First we will do sum

 

convert mixed number into improper fraction

 

2 1/6 =13/6

 

3 5/8=29/8

 

13/6 + 29/8 

 

LCM of denominators is 24

 

13* 4  / 6* 4 + 29  * 3 / 8 * 3

 

=52/24 + 87/24 

 

=139/24

 

So sum is 139/24

 

now subtract 1 1/2

 

1 1/2 = 3/2

 

139/24  - 3/2

 

LCM of denominator is 24

 

139/24 -3*12/ 2*12

 

=139/24 -36/24

 

=103/24

 

=4 7/24
