Question

6/7x=24;
7x=3/4
x:3/11=22/27
3целых3/5:x=9/35

Answer 1

6/7х=24
х=24÷6/7
х=24×7/6
х=28

7х=3/4
х=3/4÷7
х=3/4*1/7
х=3/28

х÷3/11=22/27
х=22/27×3/11
х=2/9

3 3/5÷х=9/35
18/5÷х=9/35
х=18/5÷9/35
х=18/5×35/9
х=14

Answer 2

1)6/7x=24
x=24*7/6=28;
2)7x=3/4
x=3/4:1/7=21/4=5.25;
3)3целых 3/5х=9/35
18/5х=9/35
х=9/35*5/18=1/14
