I need help with this problem Estimate the quotient by rounding the expression 1275 ÷ 588 ≈ _

1275/588 -> 1200/600=2

Step-by-step explanation:

1275 is pretty close to 1200 and 588 is pretty close to 600, so you could do 1200/600 which is 2.

Round 1275 down to 1200.

Round 588 up to 600.

We now have 1200 ÷ 600 = 2.

Done.

Step-by-step explanation:

10mm = 1cm, 100cm = 1m, 1000m = 1km

 (2.5cm 1 inch, 30cm 1 foot, 1.6km 1 mile) 5 miles = 8 km

 1000 milligrams (mg) = 1 gram (g)

 1000g = 1kg 1000kg = 1 tonne

 1000ml or 1000cm³ = 1L (litre)

 (4.5 litres 1 gallon)

 30 days have September, April, June and November, all the rest have 31,

except for February alone, which has 28 days clear, but 29 in each leap

year

 2020 is a LEAP YEAR and the next one will be in four years time: 2024

and then 2028, 2032, 2036 etc

 60 seconds = 1 minute,

 60 minutes = 1 hour,

 24 hours = 1 day,

 7 days = 1 week,

 2 weeks = fortnight,

 4 weeks is approximately one month

 one year =365 days (366 leap year)

 or 52 weeks or 12 months

 10 years = decade

 100 years = century

 1,000 years = a millennium

 £1 = 100 x 1p or 50 x 2p or 2 x 50p or 5 x 20p or 20 x 5p or 10 x 10p

 The first 12 square numbers are: 1,4,9,16,25,36,49,64,81,100,121 and

144

 The first ten prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29

2 is the only even prime number. Note that 1 is not a prime number.

 The first five cube numbers are: 1, 8, 27, 64 and 125
