ReplyDeleteWe loved the Senior problem! We figured out that 1/8 of the students were still left in class - this equated to 25 students. We worked out that if 1/8 = 25, then to find 7/8, we would need to multiply 25 by 7. This came to 175. Looking forward to tomorrow's problem! Room 6.
Room 14's answer to the junior problem:
ReplyDelete- 3? That’s half of 6
- 6 collecting flowers…. So 6 go to the hive
- You have to have the same number for each half
So Room 14’s answer is 6 bees went back to hive
7 x 25 = 175 is the answer because we added all the people in the school and - ed the people in the class. Evan,Kaelyb and Guage
ReplyDeletewe added 25 people in each group there was 8 groups 1 was in class in all we got 170 guage EVAN and kealyb
ReplyDeleteHow we worked it out was take the 25 from the amount of people still in the class and multiplied 25 x 7 = 175 which was:
ReplyDelete7 x 20 = 140
7 x 5 =35
140 + 35 =175
We got the 7 from the 7/8.

We worked it out by doing 25x7. We got 25 from the 25 students in the class which is the same as 1/8. Doing 25x7 was faster than doing repeat addition.
ReplyDeleteWe got the 7 from the 7/8 in the text. Our answer was 165 but the real answer was 175 when we worked it out with the class.
