Addition reaction: • Unsaturated hydrocarbons add hydrogen in the presence of catalysts such as Nickel and Palladium • Through this process, the unsaturated hydrocarbons get converted into the saturated ones. • This process is known as an addition reaction.
? = 21.08 + 18.99 × 21.07
13.96% of (141.17 + 158.85) + 7.95³ - (6.88 of 9.07) = ? of (58.06 - 13.02)
15.08% of (133.13 + 146.928) + 8.033 - (8.98 of 6.01) = ? of (46.09 - 20.98)
? = (5.8)2 + (8.9)2 + (4.7) 2 + 24.7% of 20
54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
[(120.96 × 12.09) ÷ ?] ÷ 6 = 19.96% of 55.07
Direction: Solve the following expression and calculate the approximate value.
(5.78 + 3.12)² + 8.2² + 2 × 8.1 × (5.9 + 3.2)
...?% of (144.31 ÷ 17.97 × 60.011) = 239.98
?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99
63.95 – 21.12 – 24.89 + 6.04 = 3.98 × ? + 3.88
