Guidelines for solving Exercise 1 on Page 79 of Math Grade 4
Problem Statement:
Calculate in two ways.
a) (8 x 23) : 4; b) (15 x 24) : 6.
Solution Method:
- Method 1: Execute operations inside the parentheses first, then outside the parentheses.
- Method 2: Apply the associative property of multiplication: (a x b) : c = a x (b : c), then perform operations inside the parentheses first, and outside the parentheses to find the most accurate result.
Answer:
a) (8 x 23) : 4 = ?
Method 1: (8 x 23) : 4 = 184 : 4 = 46
Method 2: (8 x 23) : 4 = (8 : 4) x 23 = 2 x 23 = 46
b) (15 x 24) : 6 = ?
Method 1: (15 x 24) : 6 = 360 : 6 = 60
Method 2: (15 x 24) : 6 = 15 x (24 : 6) = 15 x 4 = 60.
