Question

An ant with a mass of 4 x 10-6 kg is carrying a bread crumb back to its anthill . The bread crumb has a mass of 8 x 10-5 kg. The mass of the bread crumb is how many times the mass of the ant?​

Answer 1

Mass of bread crumb is 20 times the mass of the ant..

Explanation:

Mass of an ant =
`4* 10^(-6)` kg

Ant carries a weight of bread crumb to its anthill.

Mass of the bread crumb =
`8* 10^(-5)` kg

Ratio of their masses,

`\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=(4* 10^(-6))/(8* 10^(-5))`

`\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=(1)/(2* 10^((-5+6)))`

`\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=(1)/(20)`

Mass of the bread crumb = 20×(Mass of the ant)

Therefore, mass of the bread crumb is 20 times the mass of the ant.
