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 (3/5*8/8) + (3/8*5/5)

(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

krek1111 [17]

Purchasing power is the value of a currency expressed in terms of the amount of goods or services that one unit of money can buy. A rate of return is the annual percentage return realized on an investment, which is adjusted for changes in prices due to inflation or other external effects.
Given:
Rate of return = 3%Rate of inflation =3%
Buying Power = 3% - 3% = 0%
Thus, the buying power will remain same for the year.
