Answer 2

Answer:

Step-by-step explanation:

31/2 + 21/4

Steps:-

Convert Mixed fraction to improper fraction  

Whole number x denominator + remainder  

31/2 = 3 x 2 + 1 = 7/2

21/4 = 2 x 4 + 1 = 9/4

Add the improper fraction

7/2 +  9/4  

LCM = 8

[ 7/2   ×/×  4/4  = 14/8 ]+ [ (9 )/4   ×/×   2/2 = 18/8 ]

14/8 + 18/8 = 32/8  

Convert  improper fraction into mixed fraction

Numerator  ÷  Denominator  

32/8   =   4/8
