Nomor 2 gimana ya saya lupa ? caranya ya :))))

$3 frac{1}{4} div 2 frac{3}{4} + 1 frac{1}{2} \ = frac{13}{4} div frac{11}{4} + frac{3}{2} \ = frac{13}{4} times frac{4}{11} + frac{3}{2} \ = frac{13}{11} + frac{3}{2} \ = frac{26 + 33}{22} \ = frac{59}{22} \ = 2frac{15}{22}$

3¼:2¾+1½=
¹³/4:¹¹/4+³/2=
¹³/4×⁴/11=
52/44
=52/44+³/2=
52/44+66/44=
118/44=2 30/44
