1. round to the nearest hundred, and then subtract 4,623-3,892
a. 700
b. 600
c. 800
d. 750
2. use compatible numbers, and then divide 448 divided by 8
a. 450 ÷10 = 45
b.500÷10=50
c.500÷5=100
d. 450÷5=90
3. name the property of addition that the following equation shows 345+(452+254)= (345+452)+254
a. identity property
b. commutative property
c. associative property
d. none of the above

1. A. 731 >> 700

2. A. 450 ÷ 10 = 45 >> 56

3. C. Associative Property

Step-by-step explanation:

3. The Associative Property of Multiplication states that with the use of GROUPING SYMBOLS, no matter how you write your answer out\in-side them, you will ALWAYS get the exact same result.

2. Compatible Numbers are numbers that are easy to compute mentally, meaning that you have to physically figure out an estimate that this answer is closest to:

8 → 10

448 → 450

450 ÷ 10 = 45

448 ÷ 8 = 56

56 and 45 are close by 11, so this is the best answer.

1. 4623 - 3892 = 731 >> 700

731 rounds down to 700 because that "3" in the tens place value chart, tells the hundreds digit to start as is, and turn the rest to zeros. Always recall this:

Four or less, let it rest

Five or more, let it soar

I am joyous to assist you anytime.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

the answer is 0.3175 hope that you ^w^
