Question

Jaicee's mom says she has an hour before bed. Jenny spends 1/3 of the hour texting a friend and 1/4 of the time brushing her teeth and putting on pajamas. She spends the rest of the time reading her book. How many minutes did Jaicee read.

Answer 1

Jaicee (Jenny?) can spend 25 minutes reading.

Explanation:

1 hour is 60 minutes.



Multiply to find

1/3 of 60 minutes.

1/3 × 60

= 60/3

= 20

She spends 20 minutes texting.

Multiply to find 1/4 of 60 minutes.

1/4 × 60

= 60/4

= 15

She spends 15 minutes brushing teeth and putting on pajamas.

Subtract 20 and 15 from 60, to see what's left.



Used up time:

20 + 15

= 35

She used up 35 minutes texting and prepping for bed.

60 - 35

= 25

She has 25 minutes left for reading.
