Laila received 30 messages on her mobile phone 1 5 of them were picture messages snd 7 8 of the remainder were text messages the rest were voice messages
(A) How many text messages did she receive
(B) How many voice messages did she receive
A) To find the number of text messages, we first need to calculate the remainder after subtracting the picture messages from the total number of messages received.
30 messages - (1/5)30 messages = 30 - (6/30) = 30 - 6 = 24
So, Laila received 24 messages after excluding the picture messages.
Now, we will calculate 7/8 of the remainder to find the number of text messages.
(7/8)*24 = (7*24)/8 = 168/8 = 21
Therefore, Laila received 21 text messages.
B) The remaining messages after excluding the picture and text messages will be the voice messages.
Remaining messages = total messages - (picture messages + text messages)
= 30 - (6+21)
= 30 - 27
= 3
So, Laila received 3 voice messages.
To find the number of text messages Laila received, we need to subtract the number of picture messages from the total number of messages.
(A) Number of Text Messages:
Total messages = 30
Picture messages = 1/5 * 30 = 6
Text messages = Total messages - Picture messages = 30 - 6 = 24
Therefore, Laila received 24 text messages.
To find the number of voice messages Laila received, we need to subtract the number of picture messages and text messages from the total number of messages.
(B) Number of Voice Messages:
Picture messages = 6
Text messages = 24
Voice messages = Total messages - (Picture messages + Text messages) = 30 - (6 + 24) = 30 - 30 = 0
Therefore, Laila received 0 voice messages.
To solve this problem, let's break it down step by step:
Step 1: Calculate the number of picture messages Laila received
Since 1/5 of the 30 messages were picture messages, we can multiply 30 by 1/5:
Picture messages = 30 x (1/5) = 30/5 = 6
Step 2: Calculate the remainder after subtracting picture messages from the total
Now we need to find the number of messages that are not picture messages. We can subtract the number of picture messages from the total:
Remaining messages = 30 - 6 = 24
Step 3: Calculate the number of text messages
First, we need to find 7/8 of the remaining messages, which are text messages:
Text messages = (7/8) x 24 = (7 x 24)/8 = 168/8 = 21
So Laila received 21 text messages.
Step 4: Calculate the number of voice messages
To find the number of voice messages, we subtract the number of picture messages and text messages from the total:
Voice messages = Total messages - (Picture messages + Text messages)
= 30 - (6 + 21)
= 30 - 27
= 3
Therefore, Laila received 3 voice messages.
