Question

ROUND THE ANSWERS TO 2 DECIMAL DIGITS

1 a. 15.1/b = 33/100

1 b. 60/a = 90/32

2 a. 29/63 = 68.6/d

2 b. 49.5/d = 66.8/3.1

3 a. 89.6/d = 86/45.8

3 b. b/6 = 15/91

Answer 1

Explanation:

1 a

• 15.1/b = 33/100 ⇒ b = 15.1*100/33 ⇒ b = 45.76

1 b

• 60/a = 90/32 ⇒ a = 60*32/90 ⇒ a = 21.33

2 a

• 29/63 = 68.6/d ⇒ d = 68.6*63/29 ⇒ d = 149.03

2 b

• 49.5/d = 66.8/3.1 ⇒ d = 49.5*3.1/66.8 ⇒ d = 2.30

3 a

• 89.6/d = 86/45.8 ⇒ d = 89.6*45.8/86 ⇒ d = 47.72

3 b

• b/6 = 15/91 ⇒ b = 6*15/91 ⇒ b = 0.99
