The multiplication that Lucy has to make is:
[tex]88\times808[/tex]If she multiplies 8x808 and then multiplies the result by 2, she will not be finding 88x808, instead, she will be finding 16x808, (because 8x2 is 16):
[tex]2(8\times808)=16\times808[/tex]Thus, with that method, she will not get the correct result.
Let's find the correct method:
Going back to the original multiplication she has to make:
[tex]88\times808[/tex]We can express the number 88 as 11x8:
[tex](11\times8)\times808[/tex]And we represent this as follows:
[tex]11(8\times808)[/tex]And we have found the correct method: she has to find 8x808 and then multiply the result by 11.
Answer: Find 8x808 and multiply the result by 11.
