Answer 1

Part A)

2.7 --- 60%

Therefore in order to know what is the 100% we will do the next operation

`(1*2.7)/(0.6)=4.5`

2.7 is 60% of 4.5

Part B)

4.2 --- 10%

In order to know the 100% we will do the next operation

`(1*4.2)/(0.10)=42`

4.2 is 10% of 42

Part C)

58 --- 100%

214.6 --- ?

`(214.6*1)/(58)=3.7=370\text{\%}`

214.6 is 370% of 58
