There are 47 horses in total in a field. Next to the field there are three paddocks, each with a capacity for 10 horses.
How many horses will remain in the field once each of the paddocks is filled?
To solve this problem, we'll follow these steps:
Let's proceed with each step:
Step 1: Calculate the total capacity of the paddocks.
Each paddock can hold 10 horses. There are 3 paddocks, so the total capacity is:
Step 2: Subtract the total paddock capacity from the total number of horses.
We start with 47 horses. Placing 30 horses in the paddocks leaves:
Therefore, the number of horses that will remain in the field is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
Multiplication is more efficient! When you have equal groups, multiply to find the total quickly. 3 × 10 = 30 is faster than 10 + 10 + 10 = 30 and reduces calculation errors.
Then you'd add the individual capacities instead of multiplying. For example: if paddocks hold 8, 12, and 10 horses, total capacity = 8 + 12 + 10 = 30.
Ask yourself: "Could 17 horses fit in the field?" Since we moved 30 horses out of 47 total, having 17 remaining is reasonable - it's less than half the original amount.
The same method works! If you had 60 horses and 30 paddock spaces, then 60 - 30 = 30 horses would remain in the field. There's always enough room in the field for the extras.
Yes, but it's simple! Always do multiplication first: 3 × 10 = 30, then subtraction: 47 - 30 = 17. Following PEMDAS ensures you get the right answer.
