1.25X0.25X8.4
=1.25X0.25X(0.4+8)
=1.25X(0.25X0.4)+1.25x8x0.25
=0.125+2.5
=2.625
=1.25X0.25X(0.4+8)
=1.25X(0.25X0.4)+1.25x8x0.25
=0.125+2.5
=2.625

1.25 × 0.25 × 8.4
= 1.25 × 0.25 × (8 + 0.4)
= 1.25 × 0.25 × 8 + 1.25 × 0.25 × 0.4
= 10 × 0.25 + 1.25 × 0.1
= 2.5 + 0.125
= 2.625
= 1.25 × 0.25 × (8 + 0.4)
= 1.25 × 0.25 × 8 + 1.25 × 0.25 × 0.4
= 10 × 0.25 + 1.25 × 0.1
= 2.5 + 0.125
= 2.625
