Answer:
1. x = [tex]3\frac{5}{8}[/tex]
2. x = [tex]4\frac{3}{4}[/tex]
3. x = 125
4. x = 3
Step-by-step explanation:
Fraction = number of parts / total parts
Every fraction has a numerator that equals the number of parts we have and a denominator equaling the total number of parts in a whole.
[tex]\\ \rm\rightarrowtail x+3\dfrac{5}{8}=7\dfrac{1}{4}[/tex]
[tex]\\ \rm\rightarrowtail x+\dfrac{29}{8}=\dfrac{29}{4}[/tex]
[tex]\\ \rm\rightarrowtail x=\dfrac{29}{4}-\dfrac{29}{8}[/tex]
[tex]\\ \rm\rightarrowtail x=\dfrac{29}{8}[/tex]
[tex]\\ \rm\rightarrowtail x=3\dfrac{5}{8}[/tex]
