Answer 1

$\huge\color{pink}{\mathfrak{ᴀɴsᴡᴇʀ}}$

$\large \frac{7}{2} + \frac{9}{4} + \frac{7}{5}$

Take L.C.M. to make the denominators same.

L.C.M. of 2,4,5 =2×2×5=20

$= > \frac{7}{2} \times \frac{10}{10} = \frac{70}{20 } \\ \\ = > \frac{9}{4} \times \frac{5}{5} = \frac{45}{20} \\ \\ = > \frac{7}{5} \times \frac{4}{4} = \frac{28}{20} \\ \\ = > \frac{70 + 45 + 28}{20} = \frac{143}{20}$

$\sf \: Reduce \: it \: to \: lowest \: form = \frac{143}{20} = \frac{143}{20}$

Answer 2

Answer:

$\huge \color{black} \fcolorbox{black}{pink} { \sf{♡sσlutíσn♡\: }}$

$\frac{7}{2} + \frac{9}{4} + 6 \frac{7}{5} \\ \\ 6 \frac{7}{5} = \frac{5 \times 6 + 7}{5} = \frac{37}{5}$

Taking LCM to make the denominators same.

LCM of 2, 4, 5 = 40

Making the denominators same.

$\frac{7}{2} = \frac{7 \times 20}{2 \times 20} = \frac{140}{20} \\ \\ \frac{9}{4} = \frac{9 \times 10}{4 \times 10} = \frac{90}{40} \\ \\ \frac{37}{5} = \frac{37 \times 8}{5 \times 8} = \frac{296}{40}$

$= \frac{140 + 90 + 296}{40} = \frac{526}{40}$

Recuding to simplest form :-

$\implies \frac{526}{40} = 13.15$
