\(=\dfrac{7}{4}-\dfrac{7}{19}=\dfrac{133}{76}-\dfrac{28}{76}=\dfrac{105}{76}\)
=\(\dfrac{7}{4}\)-\(\dfrac{7}{19}\)
=\(\dfrac{133}{76}\)-\(\dfrac{28}{76}\)
=\(\dfrac{105}{76}\)
\(1\dfrac{3}{4}-\dfrac{7}{19}=\dfrac{7}{4}-\dfrac{7}{19}=\dfrac{133}{76}-\dfrac{28}{76}=\dfrac{105}{76}\)
`1 3/4 - 7/19`
`= 7/4 - 7/19`
`= 133/76 - 28/76`
`= 105/76`
