Question

Write the following numbers in the expanded forms:​

Answer 1

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 5,325 in expanded notation form is 5,000 + 300 + 20 + 5 = 5,325.

Answer 2

Explaination:❀ʀᴇǫᴜɪʀᴇᴅ ᴀɴsᴡᴇʀ:

Let the correct time for the train to complete the journey is x minuets

Then train cover distance in x+11 minuets at speed 40 km\hr = \frac{40(x + 11)}{60} km6040(x+11)km

Then train cover distance in x+5 minuets at speed 50 km\hr = \frac{50(x + 5)}{60} km6050(x+5)km

Both are same then \frac{40(x + 11)}{60} = \frac{50(x + 5}{60}6040(x+11)=6050(x+5

∴40x+440=50x+250

∴−10x=−190

∴x=19 minutes

hence the answer is x= 19 minutes
