Answer: 0.1 or 1/10

Step-by-step explanation:

$\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \:1\frac{1}{5}$

$1\frac{1}{5}=\frac{6}{5}$

$\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \frac{6}{5}$

$\frac{3}{4}-\frac{2}{3}$ $=\frac{9}{12}-\frac{8}{12}$

$=\frac{1}{12}$

$\frac{6}{5}\cdot \frac{1}{12}$

Cross, cancel common factor

$\frac{1}{2}\cdot \frac{1}{5}$

$=\frac{1}{10}$

Devon exercised the same amount of time each day for 5 days last week. e His exercise included walking and swimming. e Each day

prohojiy [21]

I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.
