lubasha [3.4K]
<span>You would have to wait 318 years for 1/5 (20%) of the Radium to disappear. 1590 is the point where half of the Radium would decay, so if you take 20% of that, it would equate out to 318 years. Radium has a long half life!</span>

Can someone explain how the answer to #14 is 7/8 in;0.875 in.
SpyIntel [72]

Hello!

That one inch is divided into eight even sections.

Look at the distance between where the insect's length ends and the "1". That space in between is how long each section is. It takes eight of those to make up one inch. The insect's length take up seven of the eight sections - almost an inch. So, the length of the insect is 7/8 in.

As for 0.875, that's the decimal form of the fraction. It means the same thing.
