Activity 3 P. 26~27 Unit 20. Fill the Pot with Water
1 . b . 4,
P. 30~31
Thomas has to use his bucket more to fill the
pot because his bucket is smaller than
Jessica’s.
When Jessica can fill the pot using her bucket
3 times, Thomas needs to use his bucket
6 times to fill up the pot. So it can be concluded
that it takes Thomas twice as many times as
Jessica. Therefore, Thomas needs to use his
bucket 4 times to fill the same pitcher.
