Can you choose answer by using different strategies to solve the following:
Aunty Reka prepared a hangi for 47 people. 19 more people came. How many came altogether?
47 + 19 = (40 + 10) + (7 + 9)
= 50 + 16
= 66
Sam did the dishes after the hangi. He washed 58 plates and 36 cups. How many dishes did he wash altogether?
58 + 36 = (50 + 30) + (8 + 6)
= 80 + 14
= 66
At the hangi, 74 pieces of chicken and 38 pieces of lamb were eaten. How many pieces were eaten altogether?
74 + 38 = (70 + 30) + (4 + 8)
= 100 + 12
= 112
Aunty Hera travelled 85 km to the hangi. She travelled another 18 km to visit her brother. How far did she travel altogether?
85km + 18km = (80km + 10km) + (5km + 8km)
= 90km + 13km
= 103km
