21/28-6/4÷9/25 pake cara tolong ya

[tex] \frac{21}{28} - \frac{6}{4} \div \frac{9}{25} \\ = \frac{3}{4} - \frac{3}{2} \times \frac{25}{9} \\ = \frac{3}{4} - \frac{75}{18} \\ = \frac{27 - 150}{36} \\ = \frac{123}{36} \\ = 3 \frac{15}{36} [/tex]

=6/4:9/25=6/4 dikali 25/9=50/12=21/28-50/12,cari KPK=84 ,63/84- 350/84=ga tau lagi maaf bangetttt cara nya kayak gitu tapi

❤Maaf kalau salah semoga membantu
