Exercise 3d with explanation


1. Evaluate: using bodmas rule


a. 0.02 × 100 + (−1.9)

b. 6.25 ÷ 2.5 – 5.5 × 1.1

c. 200.103 – 99.56 + 1.01 × 100

d. 6.6 × 0.6 + 66.6 – 0.66

e. 38.5 ÷ 0.07 – 2.4 {3 – (4.7 – 2.65)}

f. 252 ÷ 4.8 × 1.5 − (3.8 – 2.6)

Answer 1

Answer:

ans multiply 0.02 by 100 the ans you get then multiply by 1.9

Answer 2

Answer:

0.02 x 100 + (-1.9)

= 2 + (-1.9)

<=2-1-0

= 1.7

2)given expression :

= 0.05×6.252.5

= 0.31252.5

= 3.12525

= 0.125

3)200.103-99.56 +1.01 X100

200.103-99.56

200. 103-200. 56

= 400.159

4)Answer:

69.9ans

Step-by-step explanation:

6.6×0.6+66.6-0.66

3.96+66.6-0.66

70.56-0.66

=69.9ans
