Guide to Solve Problem 2 Page 62 Math 5 Textbook

Problem Statement:
Calculate using two methods:
a) (6.75 + 3.25) x 4.2; b) (9.6 − 4.2) x 3.6;

Solution Method:
Students apply the rule: (a + b) x c = a x c + a x b to solve this exercise.

Answer:

a) Method 1: (6.75 + 3.25) x 4.2 = 10 x 4.2 = 42
Method 2: (6.75+3.25) x 4.2 = 6.75 x4.2 + 3.25 x 4.2 = 28.35 + 13.65 = 42.
b) Method 1: (9.6 − 4.2) x 3.6 = 5.4 x 3.6 = 19.44.
Method 2: (9.6 −4.2) x 3.6 = 9.6 x 3.6 − 4.2 x 3.6 = 34.56 − 15.12 = 19.44.
