What is the value of the expression 5 5/12-3 1/4

ratelena [41]

Answer:

$\boxed{ \bold{2 \frac{1}{6} }}$

Step-by-step explanation:

$5\frac{5}{12} \: - \: 3 \frac{1}{4}$

It must be subtracted separately because on the one hand they are whole numbers and on the other mixed numbers.

$(5 \: - \: 3) \: + \: ( \frac{5}{12} \: - \: \frac{1}{4} )$

Mixed and whole numbers are subtracted and remain like this.

$2 \: + \: \frac{1}{6}$

We interpret it in a mixed number (fraction).

$\boxed{ \bold{2 \frac{1}{6} }}$
