Answer:

1/40 of an hour

Step-by-step explanation:

She texted her friend for 3/5 of an hour

She brushed and put pyjamas for 3/8 of an hour

To find the total time spend so we need to add 3/5 an d  3/8.

For adding these fractions we need to equate their denominator's LCM

LCM of 5 and 8 are 40

So (3/58/8) + (3/85/5)

(24/40) + (15/40)

24+15/40

39/40 of an hour.

So we can say the time spent reding by her: (40/40)  - (39/40)

i.e., 1/40
