To solve the equation: 1.1 and 3 / 5-x = 9 / 10 Write the number directly: 1 and 1 / 2-4 / 9 + =?

To solve the equation: 1.1 and 3 / 5-x = 9 / 10 Write the number directly: 1 and 1 / 2-4 / 9 + =?

1.1 and 3 / 5-x = 9 / 10
x=1+3/5-9/10
x=10/10+6/10-9/10
x=7/10;
Direct number: 1 / 2-4 / 9
=3/2-4/9
=27/18-8/18
=19/18;
