Answer these math questions.
1 .558 x 44 (and with the estimate! )
2. 9 x 802
3. 3,699 x 7
4. 34 x 93
5.678 x 87

the only one with the estimate is the first one!

1.

558 can be rounded to 600.

44 can be rounded to 40.

600 x 40 = 24,000

2.

9 x 802 = 9 (800 +2) =7200 + 18 = 7218

3.

3699 x 7 = (3700-1) x 7 = 25,900 - 7 = 25,893

4.

34 x 93 = 34 x (100-7) = 3400 - 238 = 3162

5.

678 x 87 = 58,986
