Ответ №1
3) 4,85- 2 13/24= 4 85/100- 2 13/24= 4 17/20- 2 13/24= 4 (17•6)/(20•6) - 2 (13•5)/(24•5)= 4 102/120- 2 65/120= 2 37/120
{4,85= 4 85/100= 4 (85:5)/(100:5)=4 17/20}
4) 7 8/21- 4,375= 7 8/21- 4 3/8= 7 (8•8)/(21•8)- 4 (3•21)/(8•21)= 7 64/68 - 4 63/168= 3 1/68
{4,375= 4 375/1000= 4 (375:5)/(1000:5)= 4 75/200= 4 (75:5)/(200:5)= 4 15/40= 4 (15:5)/(40:5)= 4 3/8}.
