Question

Simplify 3 3/4- 1/5

Answer 1

`(75)/(20)- (4)/(20) = (71)/(20)`

Explanation:

you have to get them both to have the common denominator, which is 20 in this case.

`3(3)/(4)` turns into

`(15)/(4\\ )\\\\[turns into this with the common denominator:]\\ (75)/(20)\\`

then subtract as seen above.

Answer 2

answer: 3 11/20

explanation: change 3 3/4 to a mixed number which is 15/4 then get a common denominator which is 75/20 - 4/20 then subtract and get 71/20 and then change to a mixed number and simplify to get 3 11/20
