Answer: (4×200)+(4×70)+(4×5)
Step-by-step explanation:
We know that 275 can be written as 200+70+5, by using properties of numbers.
Now, consider the given product
4×275
=4(200+70+5) [ by using expand property of numbers. ]
=(4×200)+(4×70)+(4×5) [by using distributive property in mental math]
=800+280+20
=1100
Here, (4×200)+(4×70)+(4×5) is the expression that can be used to find 4 x 275 using mental math and properties of numbers.
