tolong jawab no 2 dan 3

nomor 2
[tex]jumlah \: terigu \: dan \: gula = 2 \frac{1}{2 } + 3 = 5 \frac{1}{2} \\jumlah \: yg \: digunakan = \frac{3}{4} + 1 \frac{1}{4} = \frac{3}{4} + \frac{5}{4} = \frac{8}{4} = 2 \\ sisanya = 5 \frac{1}{2} - 2 = 3 \frac{1}{2}kg[/tex]
nomor 3
[tex]2 \frac{1}{4} = \frac{9}{4} \\ \frac{9}{4} \div \frac{6}{10} = \frac{9}{4} \times \frac{10}{6} = \frac{90}{24} = \frac{15}{4} \\ \frac{15}{4} \times \frac{8}{9} = \frac{120}{36} = \frac{10}{3} = 3 \frac{1}{3} [/tex]

Semoga bermanfaat
