Solving Exercise 1 Page 77 Mathematics Grade 5 Workbook

Step-by-step guide to solve exercise 1 on page 77 of the Mathematics Grade 5 Workbook

Exercise:
a) Find 15% of 320kg;                  b) Find 24% of 235m²;                           c) Find 0.4% of 350;

Solution Method:
To find a% of b, divide b by 100 and then multiply by a; alternatively, multiply b by a and then divide by 100. 

Answers:
a) 15% of 320kg is :                     b) 24% of 235m² is:                                c) 0.4% of 350 is:
    320 : 100 x 15 = 48(kg)                   235 : 100 x 24 = 56.4(m²)                         350 : 100 x 0.4 = 1.4.
