Question from Lizzy: If Patricia spent 3/8 of her time cleaning her room. She spent 2/5 as much time washing the dishes as she did cleaning her room. What fraction of time did Patricia spend Washing dishes? And it wants us to simplify our answer |
Hi Lizzy,
Suppose Patricia spend $\large \frac13$ as much time washing the dishes as she spent cleaning her room then she would have spent $\large \frac13 \normalsize \times \large \frac38 \normalsize = \frac18$ of her time washing the dishes as she did cleaning her room.
Suppose Patricia spend $\large \frac23$ as much time washing the dishes as she spent cleaning her room then she would have spent $\large \frac23 \normalsize \times \large \frac38 \normalsize = \frac14$ of her time washing the dishes as she did cleaning her room.
What if she spent $\large \frac25$ as much time washing the dishes as she did cleaning her room?
