Answer 2

（7+7/10）÷7
=7x(1+1/10)x1/7
=1+1/10
=1.1
5/8×1/12-1/4÷12=
5/8x1/12-2/8x1/12
=1/12x(5/8-2/8)
=1/12x3/8
=1/32

追答

（7+7/10）÷7
=7x(1+1/10)x1/7
=1+1/10
=1.1
5/8×1/12-1/4÷12=
5/8x1/12-2/8x1/12
=1/12x(5/8-2/8)
=(1/12)x(3/8)
=1/32

（7+7/10）÷7
=7x(1+1/10)x1/7
=1+1/10
=1.1
5/8×1/12-1/4÷12=
5/8x1/12-2/8x1/12
=1/12x(5/8-2/8)
=(1/12)x(3/8)
=1/32

（7+7/10）÷7
=7x(1+1/10)x1/7
=1+1/10
=1.1
5/8×1/12-1/4÷12=
5/8x1/12-2/8x1/12
=1/12x(5/8-2/8)
=(1/12)x(3/8)
=1/32
