Here are the step-by-step solutions for each problem on the worksheet.
1. Profile Picture Size
*
Goal: Find out how much to resize the width.
*
Given: Allowed width is 400 pixels. User's photo width is 800 pixels.
*
Calculation: Subtract the allowed size from the user's size: $800 - 400 = 400$.
*
Result: The user needs to reduce the width by 400 pixels.
2. Video Length
*
Goal: Convert time into seconds.
*
Given: 2 minutes and 45 seconds.
*
Logic: There are 60 seconds in 1 minute.
*
Calculation:
* Convert minutes: $2 \times 60 = 120$ seconds.
* Add the remaining seconds: $120 + 45 = 165$ seconds.
*
Result: 165 seconds.
3. Hashtag Usage
*
Goal: Estimate total hashtags.
*
Given: 35 posts, average of 4 hashtags per post.
*
Calculation: Multiply the number of posts by the average hashtags: $35 \times 4$.
* $30 \times 4 = 120$
* $5 \times 4 = 20$
* $120 + 20 = 140$
*
Result: 140 hashtags.
4. Followers Increase
*
Goal: Find the new follower count after a 10% increase.
*
Given: Started with 2,500 followers. Increased by 10%.
*
Calculation:
* Find 10% of 2,500: $2,500 \times 0.10 = 250$.
* Add the increase to the original amount: $2,500 + 250 = 2,750$.
*
Result: 2,750 followers.
5. Social Media Posts
*
Goal: Find the total posts for the week.
*
Given: Posted 8 times per day for a week.
*
Logic: A week has 7 days.
*
Calculation: $8 \text{ posts/day} \times 7 \text{ days} = 56$ posts.
*
Result: 56 posts.
6. Photo Resolution
*
Goal: Find the new resolution after resizing to one-fourth ($1/4$) of the original.
*
Given: Original is 1920 pixels by 1080 pixels.
*
Calculation: Divide both numbers by 4.
* Width: $1920 / 4 = 480$.
* Height: $1080 / 4 = 270$.
*
Result: 480 pixels by 270 pixels.
7. Reaction Counts
*
Goal: Estimate total reactions (likes + comments + shares).
*
Given: 1,250 likes, 780 comments, 420 shares.
*
Calculation: Add them all together.
* $1,250 + 780 = 2,030$
* $2,030 + 420 = 2,450$
*
Result: 2,450 reactions.
8. Video Views
*
Goal: Find the total number of followers.
*
Given: 1,800 views represents 60% of the followers.
*
Logic: If 60% is 1,800, we first find what 1% is, then multiply by 100 to get the total.
*
Calculation:
* $1,800 / 60 = 30$ (This is 1%).
* $30 \times 100 = 3,000$ (This is 100%).
*
Result: 3,000 followers.
9. Photo Storage
*
Goal: Calculate total storage space needed.
*
Given: 5,000 photos, each is 3 megabytes (MB).
*
Calculation: $5,000 \times 3 = 15,000$ MB.
*
Result: 15,000 MB (or 15 GB).
10. Emoji Usage
*
Goal: Estimate total emojis used.
*
Given: 25 messages, average of 3 emojis per message.
*
Calculation: $25 \times 3 = 75$.
*
Result: 75 emojis.
