Simple calculation problem of grade four: 100 has the answer.

The formula of 1, 1.2×2.5+0.8×2.5 is: ac+ab=a(b+c). Add the extracted common factor 2.5, 1.2, 0.8 to form an integer, which makes the operation simple. 1.2× 2.5+0.8× 2.5 = (1.2+0.8 )× 2.5 = 2× 2.5 = 52, 46×44/45 In this problem, 46 is converted into (45+/kloc-) by using the law of additive distribution. 46× 44/45 = (45+1)× 44/45 = 45× 44/45+44/45 = 44+44/45 = 44 and 44/45 3,1.6× 7.5× 655. 1.6× 7.5× 1.25 = 2× 0.8× 7.5× 1.25 = (2× 7.5 )× (0.8× 1.25) = 15× 65438+.250+6 16 ÷ 28× 1 5 = 250+(560+56) ÷ 28× 15 = 250+(20+2 )× 15 = 250+300.35x 62+70x 19 = 35x 62+35x2x 19 = 35x 62+35x 38 = 35×(62+38)= 100×35 = 3500
