Question

1) Find x, if 1/3 of x is 14

2)Find x ,if 1/5 of x is 14
3)Find x,if 2/5 of x is 14
4)Find x,if 7/8 of x is 14

Please explain how you got the answers! Thanks!

Answer 1

"of" means multiply and "is" means equal

1.
`(1)/(3)`x = 14

x = 14(3) multiply both sides by 3 to isolate "x"

x = 42

2.
`(1)/(5)`x = 14

x = 14(5) multiply both sides by 5 to isolate "x"

x = 70

3.
`(2)/(5)`x = 14

2x = 14(5) multiply both sides by 5

2x = 70

x = 35 divide both sides by 2 to isolate "x"

4.
`(7)/(8)`x = 14

7x = 14(8) multiply both sides by 8

7x = 112

x = 16 divide both sides by 7 to isolate "x"
