Rounding To The Nearest Whole Number. 6.7 Consider the number : It is our task to decide if the number is closer to : 6 7 Look at the number line below: or 6 7 8 6.5 6.7 Mark the number 6.5 6.5 is the midpoint between 6 and 7. Mark the number 6.7 Is 6.7 closer to 6 or 7 ? Is 6.7 above or below 6.5 ? Above 6.7 = 7 (to the nearest whole number)

What Goes In The Box ? Round the following to the nearest whole number: NB: always round 0.5 up . Ie 12.5 = 13 (to the nearest whole number). (1) 4.8 5 (6) 287.6 288 (2) 7.4 7 (7) 9.8 10 (3) 44.6 44 (8) 49.6 50 (4) 87.5 88 (9) 99.7 100 (5) 56.3 56 (10) 399.5 400

Rounding To 1 Decimal Place. Round 4.67 to one decimal place (1d.p). 4.6 4.7 4.67 4.65 What number is the arrow pointing at ? Mark 4.67 on the number line . Is 4.67 closer to 4.6 or 4.7 ? 4.7 4.67 = 4.7 (to 1d.p)

What Goes In The Box ? 2 Round the following to 1 decimal place. (1) 34.67 = 34.7 (5) 56.95 = 60 (6) 39.97 = 40 (2) 17.72 = 17.7 100 (3) 24.75 = 24.8 (7) 99.96 = (8) 999.95 = 1000 (4) 41.92 = 41.9
