Question

9 3/10 - 5 3/4 as a mixed number in simplest form

Answer 1

71/20 or 3
`(11)/(20)`

Explanation:

→ 9
`(3)/(10)` = 9 * 10 + 3 / 10

9
`(3)/(10)` = 93/10

→ 5
`(3)/(4)` = 5 * 4 + 3 / 4

5
`(3)/(4)` = 23/4

Making the denominators alike;

93 * 4/ 10 * 4 = 372/40

23 * 10 / 4 * 10 = 230/40

93/10 - 23/4 = 372/40 - 230/40

= 142/40

= 71 / 20 (simplifying by dividing both by 2) OR 3
`(11)/(20)`
