Maya has 20 bracelets and Rachel has 17 bracelets. They decide to collectively give 7 bracelets to their friend Danielle. How many do they have left?
To solve this problem, we'll follow these steps:
Now, let's work through these steps:
Step 1: Initially, Maya has 20 bracelets and Rachel has 17 bracelets.
We add these two numbers to find the total number of bracelets they have together:
Step 2: They decide to give 7 bracelets to Danielle.
To find out how many bracelets they have left, we subtract the number of bracelets given to Danielle from the initial total:
Therefore, Maya and Rachel together have bracelets remaining after giving away 7 bracelets to Danielle.
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Neither! You subtract from their combined total. Since they gave away 7 bracelets together, you need to find their total first: , then subtract: .
Then you'd subtract 7 from each person individually! Maya would have and Rachel would have for a total of 23. Always read carefully to see if it's total given or each person gives.
Look for keywords! 'Together' or 'collectively' means add their amounts first. If they're doing something as a team, combine their quantities before applying any changes.
Yes! You could think: Maya keeps and Rachel keeps all 17, giving . But the standard way (add first, then subtract) is usually clearer and less confusing.
Collectively means together as a group. When Maya and Rachel collectively give 7 bracelets, it means they gave away 7 total from their combined pile, not 7 each!
