problems/reasoning round to 1 decimal Place (IDP) 5 or more? ↑ 4 or less?! 4.8425 rounded to 1DP = 4.8 - because we need to round the 8 to I place, the 4 is our decider. the decider determines wether the number should be rounded up or down. If the decider is S or higher, round up. If the decider is a 4 or lower, round down. a 5.26715.3(1DP) 4.8325=4.83 (2DP) 1.967= 2.6(1DP) 4.8595=4.86 (2DP) 8.973 9.0 (1DP) 'What is the HCF OF SO and 80?' we could use factor trees to work this out. So 50=2x5x5 (2x5²) 80=2x2x2x2x5 (24x5) 10 we 50 100 150 200 highest common factor (HCF) = The highest number that divides exactly into two or more numbers. 250 300 350 400 80 1 8.10 4 025 /\ LCM of So and 80:400 SO 1180 80 160 240 320 406 hof-Sx2= 10 22 can also list the factors and then compare them.
