1. per share × number of shares = total number of shares = total number of shares = number of shares = number of shares.

2. 1 multiple× multiple = multiple +0 multiple = multiple +0 multiple = multiple = 1 multiple.

3. Speed × time = distance/speed = time/distance/time = speed

4. Unit price × quantity = total price ÷ unit price = total quantity ÷ quantity = unit price

5. Work efficiency × working hours = total workload ÷ work efficiency = working hours ÷ total workload ÷ working hours = work efficiency.

Formula (2)

Length unit conversion:

1 km =1000m

1 m = 10 decimeter

1 decimeter = 10/0cm

1 m = 100 cm

1 cm = 10/0mm

Area unit conversion:

1 ha = 1 10,000 m2

1 m2 = 100 square decimeter

1 square decimeter = 100 square centimeter

1 cm2 = 100 mm2

Volume (volume) unit conversion:

1 m3 = 1000 cubic decimeter

1 cubic decimeter = 1000 cubic centimeter

1 cubic decimeter = 1 liter

1 cm3 = 1 ml

1 m3 = 1000 liter

Weight unit conversion:

1 ton = 1000 kg

1 kg =1000g

1 kg = 1 kg

Currency unit conversion:

Rmb unit conversion: 1 yuan = 10 jiao.

1 angle = 10 point

1 yuan = 100 integral.

Time unit conversion:

1 century = 100 year

1 year =1February (3 1 day) Yes1\ 3 \ 5 \ 7 \ 8 \10 \1February.

Abortion lasted for 4\6\9\ 1 1 month (30 days).

February 28th in a normal year and February 29th in a leap year: 365 days in a normal year and 366 days in a leap year: 1 =24 hours: 1 =60 minutes: 1 =60 seconds: 1 =3600 seconds.
