standard_description: Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).

Estimate the following quotient. Then compute it.
$$486\div79$$
Problem 2
Divya is trying to solve
$$369 ÷ 46$$
. She estimates the quotient to be
$$369\div46 \approx 350 \div 50 = 7$$
. She starts to compute below:

.
Problem 3
723 students were divided equally into teams of 94 students for field day. Any students left over after making as many groups of 94 as possible will just be a smaller team. How many students will be on a team smaller than 94, if any?
