Answer 1

Answer:

I) 2-3/5=

(2x5)-(3xl)/5

= 7/5

2) 4+7/8=

(4x8) + (7xl)/8

=39/8

3)3/5+2/7

(3x7)+(2x7)/(5x7)

= 35/35

= 1

4 )9/11+4/15

(9xI5) +(4x1I)/(15*11)

= 179/165

do others in the same way .Its so simple

Answer 2

✅1.

$2 - \frac{3}{5} \\ = \frac{10 - 3}{5} \\ = \frac{7}{5}$

✅2.

$4 + \frac{7}{8} \\ = \frac{32 + 7}{8} \\ = \frac{39}{8}$

✅3.

$\frac{3}{5} + \frac{2}{7} \\ \frac{21 + 10}{35} ...lcm \: of \: 5 \: and \: 7 = 35 \\ = \frac{31}{35}$

✅4.

$\frac{9}{11} + \frac{4}{15} \\ = \frac{135 + 44}{165} \\ = \frac{179}{165}$

✅5.

$\frac{7}{10} + \frac{2}{5} + \frac{3}{2} \\ = \frac{7 + 4 + 15}{10} \\ = \frac{26}{10}$

✅6.

$2 \frac{2}{3} + 3 \frac{1}{2} \\ = \frac{8}{3} + \frac{7}{2} \\ = \frac{16 + 21}{6} \\ = \frac{37}{6}$

✅7.

$8 \frac{1}{2} - 3 \frac{5}{8} \\ = \frac{17}{2} - \frac{29}{8} \\ = \frac{68 - 29}{8} \\ = \frac{39}{8}$

Hope it helps you!!
