6 thoughts on “Estimating answers”

  1. 62 x 9 roughly 60 x 10= 600 so 62 x 9 is roughly 600
    48 x 12 roughly 50 x 10 =500 so 48 x 12 is roughly 500
    98 x 11 roughly 100 x 10 = 1000 so 98 x 11 is roughly 1000
    63 x 29 roughly 60 x 30 =1800 so 63 x 29 is roughly 1800
    79+39+18 is roughly 80 + 40+ 20 = 140 so 79 + 39 + 18 is roughly 140

  2. 48×12 is roughly the same as 50×10=500 so 48×12 is roughly 500
    98 x 11 is roughly the same as 100 x10=1000 so 98 x 11 is roughly 1000
    63 x 29 is roughly the same as 60 x 30 =1800 so 63 x 29 is roughly 1800

  3. 62×9 is roughly the same as 60×10=600 is roughly 600
    48×12 is roughly the same as 50×10=500 is roughly 500
    98×11 is roughly the same as 100×10=1000 is roughly 1000
    63×29 is roughly the same as 60×30=1800 is roughly 1800
