Consider the Q and A. Q: A farm is growing corn in 2 fields. One of the fields has 13 full rows of corn cobs, and the other field has 16 full rows of corn cobs. If each row contains 4 corn cobs, how many corn cobs has the farm grown?
A: 116
What is the step-by-step reasoning process?
Step-by-step reasoning process: In the first field, there are 13 rows * 4 corn cobs / row = 52 corn cobs. In the second field, there are 16 rows * 4 corn cobs / row = 64 corn cobs. So the farm has grown a total of 52 corn cobs + 64 corn cobs = 116 corn cobs.

Consider the Q and A. Q: Lake Crystal has twenty percent fewer frogs than Lassie Lake. If Lassie Lake has forty-five frogs, how many frogs are there in total in the two lakes?
A: 81
What is the step-by-step reasoning process?
Step-by-step reasoning process: Lake Crystal has twenty percent fewer frogs than Lassie Lake, a total of 20 / 100 * 45 = 9 frogs. The total number of frogs in Lake Crystal is 45 - 9 = 36. Together, the two lakes have 36 + 45 = 81 frogs.

Consider the Q and A. Q: Ryanne is 7 years older than Hezekiah. Together Ryanne's and Hezekiah's ages equal 15 years. How many years old is Hezekiah?
A: 4
What is the step-by-step reasoning process?
Step-by-step reasoning process:
Let H = Hezekiah's age. Ryanne = H + 7. 2H + 7 = 15. 2H = 8. H = 4. Hezekiah is 4 years old.
