Answer 1

Part A)

2.7 --- 60%

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

$\frac{1\times2.7}{0.6}=4.5$

2.7 is 60% of 4.5

Part B)

4.2 --- 10%

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

$\frac{1\times4.2}{0.10}=42$

4.2 is 10% of 42

Part C)

58 --- 100%

214.6 --- ?

$\frac{214.6\times1}{58}=3.7=370\text{\%}$

214.6 is 370% of 58
