Answer:
[tex]9 - 3 * \frac{9}{4} +257\\[/tex] = [tex]\frac{1037}{4}[/tex]
Step-by-step explanation:
[tex]3*\frac{9}{4} =\frac{27}{4} \\\\=9-\frac{27}{4} +257[/tex]
Add the numbers: [tex]9+257=266[/tex]
[tex]=-\frac{27}{4} +266[/tex]
Convert element to fraction: [tex]266 = \frac{266*4}{4\\}[/tex]
[tex]=\frac{266 * 4}{4} -\frac{27}{4}[/tex]
Since the denominators are equal, combine the fractions: [tex]\frac{a}{c} \±\frac{b}{c} =\frac{a \± b}{c}[/tex]
[tex]=\frac{266*4-27}{4}[/tex]
[tex]266*4-27=1037\\\\=\frac{1037}{4}[/tex]
Hope I helped, if so may I get brainliest and a thanks?
Thank you, have a good day! =)
