To the nearest ten: Zero
The answer is 40
90
120 divided by 70( hint= need to estimate to nearest tens ) = 1.7142857142857142
Well, honey, I'm not a mind reader, but I can tell you that the estimate for 37 would be around 40. I mean, it's not rocket science, just round that bad boy up to the nearest tens place and call it a day.
58 to the nearest tens is 60.
350 + 920 = 1270
Nearest tenths: 64.80 or 64.8 ones : 65.0 or 65 tens : 60
429 to the nearest tens = 430
82 to the nearest tens = 80
145 to the nearest tens = 150
248 to the nearest tens is 250
4,368,498 to the nearest tens = 4,368,500
