To take a number to two significant figures, you first take the greatest non-zero digit, and the one after it. In this case we'd have 1.0
Next you look at the third digit to see if the second digit should be rounded up, in this case the third digit is 0 so we don't round up. Thus the answer is 1.0, or written simply, 1
two sig figs

two sig figs
There are two sig figs in 3700000.
There are two sig figs in 290.

5 sig figs
Look at the numbers you are multiplying and dividing. Your answer should have the amount of sig figs that the smallest number has. Rules are as followed: .00236 Has three sig figs. The zeros are used for "spacing". (.00200 also has three sig figs.) .236 Has three sig figs. 100 Has one sig fig. 100. Has three sig figs due to the decimal point. 1.00 Has three sig figs. The rules are confusing, but with practice, you should be able to understand them without a problem. I'm sure I have also forgotten to add one or two.
