- The ratio of number of girls and boys in a class is 1:3. Set up an equation between the students of a class and boys and then draw its graph. Also find the number of boys in a class of 40 students from the graph.
- x-3/4 - 3x-7 /5 = 7/2
- what should be added to twice the rational number minus 7 by 3 to get 3 by 7
- 3x+ 4x - 90 x-?
- If you subtract 1/2 form a number and multiply the result by 1/2, you get 1/8.what is the number.
- 6x ×7x =4/6
