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

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
