Lily receives 30 messages on her cell phone. Of those messages, 1/5 are picture messages and 7/8 of the remainder are text messages. How many text messages does she receive?
1 Answer
She received 21 text messages.
Explanation:
Let's look at what we know:
There are 30 messages in total.
1/5 of the total number of messages are picture messages.
7/8 of the remainder are text messages.
Firstly, we must find 1/5 of 30, which would give us the number of picture messages.
There are 6 picture messages.
Next, we must subtract 6 from the total number of messages to find the remainder.
Finally, to find the number of text messages, we must find 7/8 of the remainder of the messages (24).
Remember: of means multiplication.
She received 21 text messages.
