Question

`3 (1)/(2) + 2 (1)/(4) - 1 (1)/(2)`
​

Answer 1

Explanation:

Step 1: Convert into improper fractions

Step 2: Find least common denominator and find equivalent fractions

Step 3 : Do the required operation

`3(1)/(2)+2(1)/(4)-1(1)/(2)=(7)/(2)+(9)/(4)-(3)/(2)\\`

Least common denominator of 2 , 4 = 4

`=(7*2)/(2*2)+(9)/(4)-(3*2)/(2*2)\\\\=(14)/(4)+(9)/(4)-(6)/(4)\\\\=(14+9-6)/(4)\\\\=(17)/(4)\\\\=4(1)/(4)`
