Answer: 1 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: Write the ratios as fractions. and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 3 x 27 = 7 x 11 81 ⇔ 77 The cross products are not equal, so the ratios are not equivalent.

| 2) Are these ratios equivalent and
Answer: 2 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 1 x 14 = 5 x 2 14 ⇔ 10 The cross products are not equal, so the ratios are not equivalent.
|
| 3) Are these ratios equivalent and
Answer: 1 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 3 x 18 = 6 x 9 54 = 54 The cross products are equal, so the ratios are equivalent.

| 4) Are these ratios equivalent 2 hot dogs : 5 hamburgers 2 hot dogs : 5 hamburgers
Answer: 1 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: Write the ratios as fractions. and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 2 x 5 = 5 x 2 10 = 10 The cross products are equal, so the ratios are equivalent.

| 5) Are these ratios equivalent
3R : 4 years 11R : 15 years
Answer: 2 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: Write the ratios as fractions. and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 3 x 15 = 4 x 11 45 ⇔ 44 The cross products are not equal, so the ratios are not equivalent.

| 6) Are these ratios equivalent
3 bags of flour : 4 bags of sugar 6 bags of flour : 8 bags of sugar
Answer: 1 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: Write the ratios as fractions. and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 3 x 8 = 4 x 6 24 = 24 The cross products are equal, so the ratios are equivalent.

| 7) Are these ratios equivalent 1 paintings for every 7 photographs 3 paintings for every 27 photographs
Answer: 2 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: Write the ratios as fractions. and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 1 x 27 = 7 x 3 27 ⇔ 21 The cross products are not equal, so the ratios are not equivalent.
|
| 8) Are these ratios equivalent and
Answer: 1 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 2 x 17 = 6 x 5 34 ⇔ 30 The cross products are not equal, so the ratios are not equivalent.
|
| 9) Are these ratios equivalent and
Answer: 2 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 3 x 16 = 4 x 12 48 = 48 The cross products are equal, so the ratios are equivalent.
|
| 10) Are these ratios equivalent 3 hot dogs : 4 hamburgers 9 hot dogs : 12 hamburgers
Answer: 2 SOLUTION 1 : Remember: Two ratios are equivalent if their cross products are equal. Solve: Write the ratios as fractions. and Compare the two cross products. Multiply the numerator of one fraction and the denominator of the other. 3 x 12 = 4 x 9 36 = 36 The cross products are equal, so the ratios are equivalent.
