Natasha spent 1/4 of the day cleaning the kitchen. She spent 1/3 of that time washing dishes. What fraction of the day did Natasha spend washing dishes? <<<< an explanation would be nice!!

moderators are

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
