f + 4 5/12 = 5 3/8

Question

does 5 = 1 19/24? I don't think so and I'm confused

Answer 1

f + 4 5/12 = 5 3/8

f = 5 3/8 - 4 5/12
f = 5 9/24 - 4 10/24
f = 4 33/24 - 4 10/24
f = 23/24

Answer 2

how did you get 4 33/24? And why don't you change 4 10/24?

Answer 3

f = 5 9/24 - 4 10/24

We need to subtract 10 from 9, so we change 5 9/24 to 4 33/24. We subtract 1 from 4 and add 1 (24/24) to the fraction.

f = 4 33/24 - 4 10/24
f = 23/24
