A weight lifter can bench press 189 kg. How many milligrams (mg) is this?
Inessa [10]

A weight lifter can bench press 189 kg. How many milligrams (mg) is this?

Answer: We know that:

1kg=1,000,000 mg

We are given, that a weight lifter can bench press 189 kg

Therefore, a weight lifter can bench press:

189 \times 1,000,000 mg

189,000,000mg

18.9 \times 10^{7} mg

Therefore, 18.9 \times 10^{7} mg is equal to the 189 kg
