841 = (8 x 102) + (4 x 101) + (1 x 100)
Take the expanded form for example 900+40+6 and make it 946. Take the first number from each set of numbers and write it and keep going until all of them are complete
5.00 + 0.20 + 0.07
It is best to make a place-value chart when trying to put a number in expanded form. Look at each digit, starting at the left (largest value) and determine it's value. Write it as a long addition equation so that the numbers in expanded form have the sum of the number you started with....So 86.093 would be: 80 + 6 + 0.09 + 0.003.When you add up the new equation you get the sum of 86.093.
Fill in the blank. "That is the (blank) thing I have ever seen!"
Yes. Make one triangle using hree matches. Underneath the two vertices at the base of this triangle, make another two triangles, using six more matches. You will find that there is an inverted triangle in the middle - the fourth.
to make numbers into exponets like 12x12x12x12x12=125
100 and 80

5.00 + 0.20 + 0.07

Expanded: (2 x 1) . (0/10) + (8/100)Word: Two and eight hundredths
0.4 = (0 x 1) . (4/10) or four tenths.
5.27 = (5 x 1) + (2/10) + (7/100)
4.012 = (4 x 1) + (0/10) + (1/100) + (2/1000)
3.842 = (3 x 1) . (8/10) + (4/100) + (2/1000)
32.06 = (3 x 10) + (2 x 1) + (0/10) + (6/100)
76.03 = (7 x 10) + (6 x 1) + (0/10) + (3/100)
