Answer :

Let's solve the given mathematical expressions step-by-step.

b) 0.426 × 300

To multiply 0.426 by 300, we can follow these steps:

  1. First, multiply 426 by 300:
    \[ 426 \times 300 = 127800 \

  2. Since 0.426 has three digits after the decimal point, we need to adjust the result by dividing by 10^3:
    \[ 127800 \div 1000 = 127.8 \

So, 0.426 × 300 = 127.8.

d) 0.94 × 7000

To find the result of multiplying 0.94 by 7000, follow these steps:

  1. First, multiply 94 by 7000:
    \[ 94 \times 7000 = 658000 \

  2. Since 0.94 has two digits after the decimal point, adjust the result by dividing by 10^2:
    \[ 658000 \div 100 = 6580 \

So, 0.94 × 7000 = 6580.
