Question 4(a)

Find using distributive property:
$728\times 101$

Answer 1

$728\times 101$

101 can be represented as (100 +1), as calculations with 100 (or any power of 10) makes it easier and faster.

Now using the distributive property,

a×(b+c) = (a×b) + (a×c), we get,

$728\times 101=728\times (100+1)$
= $(728\times 100)+(728\times 1)$
= $72800+728$
= $73528$
