@pwharris 4 is less than half of 9, so 4/9 is less than 1/2. 6 is more than half of 11, so 6/11 is more than 1/2.
Therefore 4/9 < 6/11.

@pwharris This is late I know but …
63 - 49
My brain did this:
63 - 43 - 6
20 - 6
14
Also, they are multiples of seven and there is a difference of two 7s between them. Two 7s is 14!

@pwharris No tricks is my trick. 😜

@pwharris All of those plus scuba diving.

@pwharris 1176 ÷ 48
48 x ? = 1176

@pwharris Two models, one strategy.

[Bev Malke @bevmalke1]

@pwharris 1323 ÷ 27
27 is 3x3x3
So it’s like dividing 1323 by 3 three times
(1323 ÷ 3) ÷ 3 ÷ 3
(441 ÷ 3) ÷ 3
147 ÷ 3
49

@DanikaMurray13 @pwharris Exactly how I would do this one! Can’t think of a better way!!

[Pam Harris @pwharris]

Two fantastic answers! @bevmalke1 @davidwees

Is one more 'right' than the other?

How would you handle getting both of these answers in a classroom?

@pwharris A 16 minute mile… So that is
5280/16 feet per minute
2640/8 feet per minute
1320/4 feet per minute
660/2 feet per minute… oooo that is easy to change to seconds
11/2 feet per second
5.5 feet per second

@pwharris My immediate thought was
(a-b)(a+b) but of course I wanted to try using a ratio table…worked out kinda nice!

@pwharris 49 + 28
My brain added 40 + 20, then 9 + 8, to get 60 + 17 = 77

@pwharris 3618 - 2412
3(1206) - 2(1206)
= 1206

@pwharris 14 is 35% of ___

[Bev Malke @bevmalke1]

@pwharris 76 x 44
The ratio table strikes again!
