36×25=36□÷4

36×25 =9×(4×25) =9×100 =900

36X25 =9×4×25 =(36÷4)×(25×4)

36×25=(36÷4)×(25×4) =9×100 =900

解: 36.25÷4.25x9.99 =36.25÷17/4x9.99 =36.25x4/17x9.99 =(36x4+0.25x4)x(10-0.01)÷17 =(144+1)x(10-0.01)÷17 =145x(10-0.01)÷17 =(145x10-145x0.01)÷17 =(1450-1.45)÷17 =1448.55÷17 =1700分之144855 =340分之28971 ≈85.208823...

36.72÷4.25x9.9 =8.16x9.9 =8.16×(10-0.1) =8.16×10-8.16×0.1 =81.6-0.816 =80.784

36.72÷4.25x9.9 =918/25÷17/4×9.9 =216/25(10-0.1) = 8.64(10-0.1) =85.536

36.72÷4.25=8.64

36.72÷4.25×99 =8.64×(100-1) =864-8.64 =855.36。

36.72÷4.25×6.6 =8.64x6.6 =57.024

36除与三分之四
