Multiplying & Dividing Sig Figs: RULE: When multiplying or dividing, your answer may only show as many significant digits as the multiplied or divided measurement showing the least number of significant digits. 13.7 x 2.5 = 200 x 3.58 = 0.00003 x 727 = 5003 / 3.781 = 89 / 9.0 = 5000 / 55 = 3.14 x 5.6= 300 x 10.6= 0.059 x 6.95= 80/0.675=

When multiplying or dividing, the answer will have the same amount of sig figs as the value with the least number of sig figs. If the answer has too many decimal places, round to the number of sig figs it should have. For example, 12 / 3.00 = 4 ( 4.0. 12 has two significant figures and 3.00 has three, so the answer should only have two.
