Solve the following multiplication and division problems. a. 10 yd. × 3 yd. b. 15 ft. × 18 ft. c. 13 yd. 2 ft. 6 in. × 15 d. 198 sq. yd. 8 sq. ft. × 7

To solve these problems, we just need to multiply or divide.

To solve problem c and d, we need to transform all units to the same, and then operate.

Remember that

To solve this one, we need to transform all lengths to yards. We know that 1 yard equals 3 feet and 1 feet equals 12 inches. So,
