Answer 2

Answer:

a) The value of 10% of 1 hr is 0.1 hr.

b) 5% of 12000 is 600​ .

Step-by-step explanation:

Given -

a) 10% of 1 hr

b) 5% of its 600​

To find -

a) The value of 10% of 1 hr

b) 5% of what is 600​

Solution -

Percentage means divide by 100.

a) The value of 10% of 1 hr

We can write it as,

The value of 10% of 1 hr  = $\frac{10}{100} \times 1$

The value of 10% of 1 hr  = $\frac{1}{10}$

Divide 1 by 10 we get

The value of 10% of 1 hr  = $0.1$

∴ The value of 10% of 1 hr is 0.1 hr.

b) 5% of what is 600​

let, the value is x

we write it as,

$\frac{5}{100}\times x= 600$

$x=600\times\frac{100}{5}$

Divide 600 by 5 we get

$x= 120\times100$

$x=12000$

∴ 5% of 12000 is 600​ .
