Explain how the picture you drew shows groups of equal size.
Answer:
Each cake is of same size and each cake needs 3 apples.
Total four cakes made up of 3 apples each, so total 12 apples are used to make 4 cakes.

Another Way Multiply.

When you combine equal groups, you can multiply to find how many in all.

Draw 3 counters in each circle.

Since there are the same number of counters in each circle, you can multiply to find how many in all.

Multiplication is another way to find how many there are altogether in equal groups.

Elena collected 431 bottles for recycling. Pete collected 227 fewer bottles than Elena. How many bottles did Pete collect?

What do you need to find?
Answer: 204
Explanation:
Elena collected 431 bottles for recycling.
Pete collected 227 fewer bottles than Elena.
Number of bottles collected by Pete
431 – 227 = 204

Circle the numbers you need to use.
Answer:

Explanation:
Numbers that are used to circle are Elena collected bottles and Pete collected bottles.

Combine place values to find the difference.

A. Subtract. 431 – 227
Estimate. 400 – 200 = ________
STEP 1: Look at the ones place. Since 7 > 1, combine place values. Combine the tens and ones places. There are 31 ones and 27 ones. Subtract the ones. Write 0 for the tens.

Estimate. 400 – 200 = 200

STEP 2:
Subtract the hundreds.
So, Pete collected _________ bottles.
Since ___________ is close to the estimate of _________, the answer is reasonable.

Answer:
So, Pete collected 204 bottles.
Since 204 is close to the estimate of 200, the answer is reasonable.
Explanation:
To find a value that is close enough to the right answer,
usually with some thought or calculation involved. is called estimate.
So, the estimate of 204 is 200.

Answer:

Explanation:
From the given data,
The largest yellowfin tuna weighs 427 pounds.
The largest grouper weighs 436 pounds.

One Way: Use compatible numbers.
Think: Compatible numbers are numbers that are easy to compute mentally and are close to the real numbers.

So, the grouper weighed about _______ pounds more than the yellowfin tuna.
Answer:
10 pounds

Explanation:
436 and 427 are written in place value round figures as 435 and 425 and
