# Question #924ee

##### 1 Answer

#### Answer:

**(d)**

**(e)**

#### Explanation:

When it comes to *multiplication* and *division*, the rule to go by in terms of significant figures is that the answer **cannot** have more sig figs than the number with the *least* number of sig figs.

What this means is that you always need to keep an eye out for the number that has the *least* number of sig figs because that's how many sig figs the answer must have.

In your case, you have

#7.4/3" "# and#" "12.4 * 0.30#

In the first example, you have

#7.4 -># *two sig figs, 7 and 4*#3 -># *one sig fig, 3*

This means that the answer must have **1 sig fig**, since that's the smallest number oif sig figs you get for your two numbers.

#7.4/3 = 2.46667 = color(green)(2)#

In the second example, you have

#12.4 -># *three sig figs, 1, 2, and 4*#0.30 -># *two sig figs, 3 and the zero after the decimal*

This tells you that the result cannot have more than two sig figs

#12.4 * 0.30 = 3.72 = color(green)(3.7)#
