Question

Write 3 1/2 as a decimal number

Answer 1

Answer:

3 .1 /2 = 3.50 = 350 %

Step-by-step explanation:

To convert a fraction into decimal, one needs to transform it so that the fraction is a sum of fractions each or which has a denominator, which is a power of  10.

3 .1/ 2 =  3 1 × 50 /2 × 50  =  3 .50 /100  = 3.50

And for conversion to percentage, one needs to multiply this by  

100

Hence  

3 .1/ 2 =  3.50  =  ( 3.50 × 100 )%  =  350 %
