CHAPTER 5 :
EXERCISE # 5.1
QUESTION # 7
= 1.4/5 ÷ [ 1/25× { 1. 1/4 + ( 3. 1/3 ÷ 2. 1/2 × 1. 5/16 )}] × 1/2
= 9 / 5 ÷ [ 1/25 × { 5 / 4 + ( 10/3 ÷ 5/2 × 21/16 )}] × 1/2 → 1st step after using division method
= 9 / 5 ÷ [ 1/25 × { 5/4 + ( 10/3 × 2/5 × 21/16 )}] × 1/2 → 2nd step cut the numbers change signs by
multiplication method .
= 9 / 5 ÷ [ 1/25 × { 5 / 4 + 7 / 4 }] × 1/2 → 3rd step small bracket solve
= 9 / 5 ÷ [ 1/25 × 5 + 7 / 4 ] × 1/2 → 4th step middle bracket solve
= 9 / 5 ÷ [ 1/25 × 12/ 4 ] × 1/2 → 5th step now we solve square bracket
= 9 / 5 ÷ 3 / 25 × 1 / 2 → 6th step all brackets solve
= 9 / 5 × 25 / 3 × 1 / 2 → In this step division sign change into multiple sign
= 15 / 2 → 7th step by using simple division method
= 7. 1 /2 → Is Answer .
