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.

30×15=6

There are 6 picture messages.

Next, we must subtract 6 from the total number of messages to find the remainder.

306=24

Finally, to find the number of text messages, we must find 7/8 of the remainder of the messages (24).

Remember: of means multiplication.

24×78=21

She received 21 text messages.
