First of all... Who would name their kid dott??!?!!
Decimal time:
1 2/3= 1.666, forever
2 7/10= 2.7
1 1/2= 1.5
1.6666 forever times 1.5 = the amount of tomatoes she ate yesterday. = 2.5
1.666 forever times 2.7 = the amount of tomatoes she ate today. = 4.5
4.5 - 2.5 = 2
She ate 2 more tomatoes today than she did yesterday.
