We have started a new topic for Mathematics about Fractions.
Today we talked about because we knew...
1/2 of 10=5 we also knew...
1/2 of 30=15 1/2 of 6=3 1/2 of 12=6 1/2 of 18=9
1/2 of 20 = 10 1/2 of 100 = 50
1/2 of 40 = 20 1/2 of 1 000 = 500
1/2 of 80 = 40 1/2 of 10 000 = 5 000
1/2 of 160 = 80 1/2 of 100 000 = 50 000
1/2 of 320 = 160 1/2 of 1 000 000 = 500 000...
1/2 of 640 = 320
1/2 of 1 280 = 640
1/2 of 2 560 = 1 280...
1/4 of 10 = 2.5 1/2 of 10 = 5 3/4 of 10 = 7.5 so...
1/4 of 1 = 0.25 1/2 of 1 = 0.5 3/4 of 1 = 0.75
