Question

i have to estimate each product or quotient are these right?
-72 x 57 i got:
-70 x 60 - -4200

-92 x (-41) i got
3600

-83 x 52 i got:
-80 x 50 = -40000

-803 x (-106) i got
-800 x (-100) = 80000

49 x 61 i got 50 x 60 = 3000

i don't know about these division ones
-476 / 90
-500/ 90 ?

538 / (-63)
500 / 60 ?

479 / (-61)
500 / (-60)?
Ms. Sue
I agree with your estimates.

For this one, I'd find a multiple of 90

476 = 450
450/90 = 50

Do the same for the others.



SO IT WOULD BE -476 / 90
ESTIMATE IS -450 / 90 IS -5

IM NOT UNDERSTANDING ESTIMATE FOR
538/ (-63)

479 / (-61)
Ms. Sue
Multiples of 60: 60, 120, 180, 240, 300, 360, 420, 480, 540

Which is closest to 476?

closest to 476 is 480
Ms. Sue
Right.

480/60 = ?
