someone help me with this splz

Change in weight
[tex] = 1 \frac{3}{4} - \frac{1}{4} [/tex]
[tex] = \frac{7}{4} - \frac{1}{4} [/tex]
[tex] = \frac{7 - 1}{4} [/tex]
[tex] = \frac{6}{4} [/tex]
[tex] = \frac{3}{2} [/tex]
Rate of weight change
[tex] = \frac{3}{2} \div \frac{1}{4} [/tex]
[tex] = \frac{3}{2} \times 4[/tex]
[tex] = 3 \times 2[/tex]
[tex] = 6[/tex]
