Question

An ant weighs 2 x 10^-3 grams, and a lion weighs 1 x 10^5. The lion's weight is 5 x 10^x times greater than the ant's weight. What is the value of x?

x = ?

Answer 1

x=7

Explanation:

Information provided

Weight of ant=
`2*10^(-3) grams`

Weight of lion=
`1*10^(5)` but units are not provided, assuming this unit is also grams

How many times lion's weight exceed an ant

`\frac {1*10^(5)}{2*10^(-3)}=50000000`

=
`5*10^(7)`

Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant
