A school has 3,278 pencils to place equally into 45 class bins.
How many pencils can go into each bin, and how many will be left over?
72 pencils per bin with 38 pencils left over.
Where should the parentheses be inserted to make the equation true?30 x 80 + 4 + 16 = 3,000
30 x (80 + 4 + 16) = 3,000
Compare using <, >, = WITHOUT completely evaluating:
(72,000 + 8,000)/40____72,000/40

without doing long division: 6,300,000 divided by 104
104= so dividing by 104 makes the number 10,000 smaller.
A student says 824 x 57 = 46, 968.
Is he correct? Explain.
Yes. 824 x 50 = 41,200
824 x 7=5,708
41,200 + 5,70= 46,968
