Question

Marcia dusts 3/4 of her cabinets with 1/3 bottle of dusting polish at this rate what fraction of the bottle of dusting polish will Marcia use dust all of her cabinets

Answer 1

Marcia will use 4/9 of the bottle of dusting polish to dust all of her cabinets.

Step-by-step explanation:

To find the fraction of the bottle of dusting polish that Marcia will use to dust all of her cabinets, we need to find the total fraction of the bottle she uses to dust 3/4 of her cabinets and then multiply it by the reciprocal of 3/4.

So, if Marcia uses 1/3 of the bottle to dust 3/4 of her cabinets, she will use (1/3)*(4/3) = 4/9 of the bottle to dust all of her cabinets.
