Which mixed number is equivalent to the decimal 5.2

Answers

5 1/5 can be equal because since it is five and two tenths ( it is 5.2 in word form), it can be 5 2/10 but I simplified the fraction and my answer is 5 1/5

Lets do it:-

5.2
5.2/1
$(5.2*10)/(1*10)= (52)/(10)$

Convert 52/10 in to a mixed number:-

52 ÷ 10 = 5.2

Mixed number =

$5(2)/(10)$

So, the decimal is equivalent to 5 1/5.
