10. < < < 6 5 < Because 27 is closer to 25 than to 36, is close to 5 than to 6. Because 27 is closer to 27.04 than 26.01, is closer to 5.2 than to 5.1. Example 1: Estimating Square Roots Estimate to the nearest tenth. Find the two perfect squares that 27 lies between. Find the two integers that lies between . Try 5.2: 5.22 = 27.04 Too high, try 5.1. 5.12 = 26.01 Too low Check On a calculator ≈ 5.1961524 ≈ 5.1 rounded to the nearest tenth. 
