Luda [366]

Answer:

First option

Step-by-step explanation:

Given the following equation:

$\frac{1}{4} \times(\frac{3}{9} +5)$

In order to find the answer, we solve the equation in between the parenthesis according to order of operations and then multiply that answer by 1/4.

$\frac{1}{4} \times(\frac{3}{9} +5)$
$5=\frac{5}{1}$
$\frac{3}{9} +\frac{5}{1}$
$3\times1=3$
$9\times1=9$
$5\times9=45$
$1\times9=9$
$\frac{3}{9} +\frac{45}{9}$
$3+45=48=\frac{48}{9}$
$\frac{48}{9} \div3=\frac{16}{3}$

$\frac{1}{4} \times\frac{16}{3}$
$1\times16=16$
$4\times3=12$
$\frac{16}{12} \div2=\frac{8}{6} \div2=\frac{4}{3}$
$\frac{4}{3} =4\div3=1\frac{1}{3}$
$=1\frac{1}{3}$

Hope this helps.
