Guidance on solving exercise 4 on page 78 of Math 4 textbook
Problem:
Calculate using two methods:
a. (33164 + 28528) : 4 b. (403494 - 16415) : 7
Solution Method:
- Method 1: Execute calculations inside the parentheses first, outside the parentheses afterward
- Method 2: Apply the calculation method: (a + b) : c = a : c + b : c or (a - b) : c = a : c - b : c
Answer:
a. (33164 + 28528) : 4 = 61692 : 4 = 15423
(33164 + 28528) : 4 = 33164 : 4 + 28528 : 4 = 8291 + 7132 = 15423
b. (403494 - 16415) : 7 = 387079 : 7 = 55297
(403494 - 16415) : 7 = 403494 : 7 - 16414 : 7 = 57642 - 2345 = 55297
