Question

27/10×5/36等于几分之几有过程？

Answer 1

这道题是将两个数的分子乘以分子、分母销带友乘以分母，然后亏槐约分，27和36的最大公约行帆数是9、5和10的最大公约数是5
27/10×5/36
=27×5/10×36
=3×1/2×4
=3/8

Answer 2

这个可销告以约扰斗链分，找分子分母的公约数。
27/缓孙10×5/36
=27×5/(10×36)
=3×9×5/(5×2×4×9)
=3/(2×4)
=3/8

Answer 3

27/10×5/36
=27/36×5/10
=3/4×1/2
=3/8

Answer 4

27/腔运培10ⅹ5/36
=(27÷9/10÷5)ⅹ(5÷5)/伍唯悄森(36÷9)
=3/2ⅹ1/4
=3/8

Answer 5

27/10×5/36
= 3/4 × 5/10
= 3/4 × 1/2
= 3/8
