Answer 2

4 3/4 -2 2/4= 2 1/4

7 2/5 - 5 5/6= 37/5 - 35/6 = 444/60 - 350/60 = 94/60 = 47/30 = 1 17/30

3  1/5 :1 1/7= 16/5 : 8/7 = 16/5 * 7/8 = 14/5 = 2 4/5 (sorry za pomyłkę)

6 1/2 * 1  1/7= 13/2 * 8/7 = 52/7 = 7 3/7

5 3/4: 19/21= 5 3/4 * 21/19 = 24/4 * 21/19 = 483/76 = 6 27/76

5/9 masy 36kg tj. 20 kg

3,75:2,5=1,5

3/4 dl. 280cm tj.210 cm

48,16:0,16=301

57,2:2,4=23,8(3)

4,2* 5,7=23,94

26,8*1,62=43,416

4,07 * 3,4=13,838

280,7-149,63=131,07

50-19,63=30,37

300,2-27,896= 272,304
