Terima kasih sebelumnya
Tolong dibantu ya Cara atau Jalan penyelesaiannya bagaimana
A.27332 b.235 c.552 d.59
A. 4795 – (-22,537) =4795 + 22,537=27332
B. (473+(-287))+149=(473-287)+149=186+149=335
C. 867+(-315)=867-315=552
D. 98+63:7-16×3=98+9-48=59
E. (5 3/4 + 4 1/8) – 2 1/2= (23/32 + 33/32)-5/2=(56/32)-5/2=112/64 – 160/64= – 3/4
F. 2/7 × 6,3 : 12/100 = 2/7 × 63/10 × 100/12=2 ×9/10 × 100/12 = 12×9×10/12=9×10/6=9×5/3=3×5=15
G. 635 – (-27)-450=635+27-450=662-450=212
H. 84 × (-9)= -756
