Question

Which sets of ordered pairs show equivalent ratios? Use the grid to help you. Check all that apply. (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

Answer 1

The pairs (2, 2), (4, 4), and (6, 6) have ratios of 1 and the pairs (4, 1), (4, 1),      (8, 2), and (12, 3) have ratios of 4. The other pairs do not have similar ratios.

Step-by-step explanation:

Step 1; In order to pair up the pairs with equivalent rations, we first need to calculate the ratios for all the pairs by dividing the first value with the second value. The same procedure must be followed throughout to be able to pair them up.

Step 2; By dividing the values, the ratios are;

For (1, 2), the ratio is $\frac{1}{2}$ = 0.5,

For (2, 3), the ratio is $\frac{2}{3}$ = 0.6666,

For (4, 7), the ratio is $\frac{4}{7}$ = 0.5714,

For (2, 2), the ratio is $\frac{2}{2}$ = 1,

For (4, 4), the ratio is $\frac{4}{4}$ = 1,

For (6, 6), the ratio is $\frac{6}{6}$ = 1,

For (3, 1), the ratio is $\frac{3}{1}$ = 3,

For (4, 1), the ratio is $\frac{4}{1}$ = 4,

For (5, 1), the ratio is $\frac{5}{1}$ = 5,

For (4, 1), the ratio is $\frac{4}{1}$ = 4,

For (8, 2), the ratio is $\frac{8}{2}$ = 4,

For (12, 3), the ratio is $\frac{12}{3}$ = 4,

For (2, 1), the ratio is $\frac{2}{1}$ = 2,

For (4, 3), the ratio is $\frac{4}{3}$ = 1.333,

For (5, 4), the ratio is $\frac{5}{4}$ = 1.25.

Step 3; Now we pair up the sets with the same ratios, out of these 15 pairs. The pairs (2, 2), (4, 4), and (6, 6) have ratios of 1 and the pairs (4, 1), (4, 1),      (8, 2), and (12, 3) have ratios of 4. The other pairs do not have similar ratios.

Answer 2

Answer:

The answer is

1,4

2,8

3,12

Step-by-step explanation:

I if you read the box from x to y the number are matching up from up to down so the number on the top of the box is first and then the number on the bottom of that is the second number but they still both match up...

You will only understand if your on the assessment looking at the box
