г)3/8×9/11=
д)5 3/5×1 4/21=
е)(1 11/4-1 3/10):7/5=

Answer 1

а) 9-5 4/11 = 9 - 20/11 = 79/11 = 7 2/11

б) 5 5/12 : 7/36 = 5 * 5/12 * 36/7 = 5*5 3/7 = 75/7 = 10 5/7

в) 8 1/3 : 2 2/3 = 8 * 1/3 * 1/2 * 2/3 = 8* 1/3*1/3 = 8/9

г)3/8 * 9/11 = 3*9 / 8*11 = 27/88

д)5 3/5 * 1 4/21 = 4/7

е)( 1 11/4 - 1 3/10 ) : 7/5 = ( 11/4 - 3/10 /* 5/7 = 49/20 * 4/7 = 7/4 = 1 3/4
