Maria wanted to bring back 5 million grains of sand from her trip to the beach. Each grain of sand weighs approximately 6.7×10^−7 kg. How heavy is the bag of sand that Maria brings home?(1 point) Responses
Multiply
5,000,000 (6.7 x 10^-7)=(5 x 10^6) * (6.7 x 10^-7)= (5 x 6.7) (10^6 +^(-7)=___kg
Multiply
5(6.7 x 10^-7)=33.5 x 10^-7=3.35 x 10^-6 kg
Multiply
5,000,000(6.7 x 10^-7)=(5 x 10^6) * (6.7 x 10^-7)= (5 * 6.7) (10^6+7)=3kg
Divide
1 answer
5,000,000 / (6.7 x 10^-7) ≈ 7.46 x 10^13 kg
