3/10 X x = 42

x = 420 / 3

x = 140

Answer 2

Answer:

The number will be$140$.

42 is 30% of 140.

Step-by-step explanation:

Given: $30\% \ of\ x =42$

We have to find 42 is 30% of which number.

We are solving on the following way:

To find 42 is 30% of which number we will assume the numbers will be$x$.

From the given statement we can write;

$30\% \ of\ x =42$

As we know that, a percentage is a fraction of an amount is expressed as a particular number of hundredths of that amount.

So,

$30\% \ of\ x =42$

$=>\frac{30}{100} \times x=42$

Solving the above further we get,

$=>\frac{30x}{100} =42\\\\=>30x=42\times 100\\=>30x=4200\\\\=>x=\frac{4200}{30} \\\\=>x=\frac{420}{3} \\\\=>x=140$

The number will be$140$.
