Back

91

Front

Would (16,14) be an equivalent ratio on the graph?

Back

No

Front

Would (3,2) be an equivalent ratio on the graph?

Back

Yes

Front

Choose the Point that will NOT go on the graph: (1,3), (2,6), (4,16), (10,30)

Back

(4,16)

Front

Would (18,12) be an equivalent ratio on the graph?

Back

Yes

Front

What is an equivalent ratio?

Back

An equivalent ratio is a ratio that expresses the same relationship between two quantities, even if the numbers are different.

Front

How do you determine if two ratios are equivalent?

Back

Two ratios are equivalent if their cross products are equal.

Front

What is the formula for finding the total number of beads used if you know one type?

Back

Total beads = Number of black beads + Number of other beads.

Front

What does the point (x,y) represent on a graph?

Back

The point (x,y) represents a location on the Cartesian plane where 'x' is the horizontal coordinate and 'y' is the vertical coordinate.

Front

What is the significance of the graph in understanding ratios?

Back

The graph visually represents the relationship between two quantities, making it easier to identify equivalent ratios.
