Question

Split the factors and solve the problems using re-arrangement

$25\times 28=\_\_$

Answer 1

We have- $25\times 28=\_\_$

We can split $28$ into its factor as $4\times 7$

Then, $25\times 28=25\times 4\times 7$

$=100\times 7$ ($4$ times the $25$ is $100$)

$=700$ ($7$ times the $100$ is $700$)

Hence, $25\times 28=700$
