Question

0.001225 kg/L x 720 000 000L =?

Answer 1

0.001225 kg/L × 720 000 000 L = 882000 kg

Step-by-step explanation:

Given:

The equation to solve is given as:

0.001225 kg/L × 720 000 000 L = ?

Let us write each term of the product in terms of power of 10.

As 0.001225 has 6 digits after the decimal place, therefore, we use the exponent 6 for 10 and the sign is negative. This gives,

`0.001225\ kg/L = 1225* 10^(-6)\ kg/L`

Now, for 720000000 L there are 6 zeros after 720. So, we use exponent 6 but with a positive sign. This gives,

`720000000\ L=720* 10^(6)\ L`

Now, finding the product, we get:

`0.001225\ kg/L* 720000000\ L\\\\=1225* 10^(-6)\ kg/L* 720* 10^6\ L\\\\=(1225* 720)* (10^6* 10^(-6))\ ((kg)/(L)* L)\\\\=882000* 10^(6-6)\ kg\\\\=882000* 10^0\ kg\\\\=882000* 1\ kg\\\\=882000\ kg`

Therefore, the product is equal to:

0.001225 kg/L × 720 000 000 L = 882000 kg
